Choosing between equally and equality is a common challenge for writers, students, and professionals alike. Both words stem from the exact same root concept—sameness, fairness, and balance—yet they perform completely different jobs in a sentence. Using one where the other belongs creates awkward phrasing and clear grammatical errors that can undermine your writing.
You might wonder whether a team should be “paid equality” or “paid equally,” or whether an organization is striving for “racial equally” or “racial equality.” While your audience might guess your intended meaning, confusing an adverb with a noun signals a lack of polish in business communications, academic essays, and official documents.
Understanding the difference between equally vs equality does not require a degree in linguistics. It comes down to identifying whether you are describing how an action happens or naming the concept of sameness itself. This comprehensive guide breaks down the precise grammatical rules, highlights common mistakes like the redundant “equally as,” provides diagnostic mental shortcuts, and gives you clear examples so you never second-guess your choice again.
Quick Answer
The difference between equally and equality is entirely a matter of grammar and part of speech:
- Equally is an adverb. It describes how an action is performed or to what extent a trait is shared (“to an equal degree or in equal measure”).
- Equality is an abstract noun. It names the concept, state, or condition of being equal in rights, status, value, or opportunity.
Equally = Adverb (Modifies verbs & adjectives) -> "They shared the task equally."
Equality = Noun (Names a concept or state) -> "They fought for income equality."
Because adverbs modify actions or qualities while nouns represent things or ideas, these two words are never grammatically interchangeable. If your sentence needs a word to modify an action or an adjective, use equally. If your sentence needs a subject or a direct object to represent the idea of fairness or sameness, use equality.
Why People Confuse Them
The confusion surrounding equally and equality stems from three primary linguistic factors: shared etymology, shared adjective base, and structural translation shifts when constructing complex thoughts.
1. Shared Latin Root and Base Adjective
Both terms originate from the Latin root aequus, meaning “even,” “fair,” or “equal.” In modern English, both words build upon the base adjective equal. Because both words carry identical core themes—fairness, uniform distribution, and identical value—writers often focus on the overarching meaning of “sameness” rather than checking the sentence’s grammatical machinery.
2. Overlapping Thematic Contexts
In discussions surrounding workplace fairness, civil rights, economic policy, and mathematics, both terms appear frequently. A writer might read about “income equality” in one paragraph and read that bonuses were “distributed equally” in the next. Because the subjects and settings are identical, it is easy to blur the line between the condition being sought (equality) and the manner in which resources are provided (equally).
3. Structural Shifts in Sentence Construction
When people translate thoughts into written sentences, they often shift between describing an action and naming a state. Consider these two thoughts:
- “We want everyone to be treated in an equal manner.” $\rightarrow$ “We want everyone treated equally.” (Adverb modifying the verb treated)
- “We want everyone to enjoy equal status.” $\rightarrow$ “We want equality for everyone.” (Noun serving as the object of the sentence)
When a writer mixes these two sentence patterns, they end up with hybrid mistakes like “We want everyone treated equality” or “We want equally for everyone.” Identifying the grammatical target of your sentence resolves the confusion immediately.
Key Differences At A Glance
To determine whether your sentence requires equally or equality, review this direct context lookup table:
| Context | Best Choice | Why |
| Modifying an adjective (e.g., important, capable) | equally | Adverbs are required to modify adjectives to show degree |
| Describing how a verb action is done (e.g., split, share) | equally | Adverbs modify verbs to show the manner of an action |
| Naming a political, social, or legal concept | equality | Abstract nouns are required to name concepts and rights |
| Serving as the direct object of a verb (e.g., demand, achieve) | equality | Verbs take noun phrases as direct objects, not adverbs |
| Following a preposition (e.g., strive for, belief in) | equality | Prepositions require noun objects to complete the phrase |
| Comparing two qualities without duplicating words | equally | Functions as an adverbial degree modifier (equally valuable) |
Meaning and Usage Difference
Understanding how equally and equality function within sentence structure is the key to error-free writing. Let’s examine the mechanics of each word in detail.
Mechanics of “Equally” (The Adverb)
As an adverb, equally answers the questions How?, In what manner?, or To what degree? It never stands alone as a noun concept. Instead, it must attach itself to an adjective, a verb, or another adverb.
1. Modifying Adjectives (Degree)
When equally modifies an adjective, it tells the reader that two or more things share a quality to the exact same extent:
- “Both proposals are equally persuasive.” (Equally modifies the adjective persuasive)
- “She presented two equally compelling arguments.” (Equally modifies the adjective compelling)
2. Modifying Verbs (Manner or Distribution)
When equally modifies a verb, it describes how an action is carried out across multiple parties or parts:
- “The inheritance was divided equally among the three siblings.” (Equally modifies the verb divided)
- “The manager treated all team members equally.” (Equally modifies the verb treated)
[Subject] + [Action Verb] + [Direct Object] + EQUALLY (Adverb)
Example: The team + distributed + the workload + equally.
Mechanics of “Equality” (The Noun)
As an abstract noun, equality represents the entity, concept, or state of being equal. It functions like any other noun in English: it can act as the subject of a sentence, the direct object of a verb, or the object of a preposition.
1. Functioning as a Subject or Direct Object
- “Equality is a foundational principle of democracy.” (Equality is the sentence subject)
- “The organization promotes equality in the tech industry.” (Equality is the direct object of promotes)
2. Functioning as the Object of a Preposition
- “Citizens marched in support of equality.” (Equality is the object of the preposition of)
- “There can be no true freedom without equality.” (Equality is the object of the preposition without)
[Subject] + [Action Verb] + EQUALITY (Noun Direct Object)
Example: Our society + seeks + equality.
Comparative Structural Summary
To see how their functions differ side by side, examine their grammatical traits:
| Feature | equally | equality |
| Part of Speech | Adverb | Abstract Noun |
| Primary Function | Modifies verbs, adjectives, and adverbs | Names a state, principle, condition, or concept |
| Question Answered | To what degree? or In what manner? | What state or concept is being discussed? |
| Sentence Role | Adverbial modifier | Subject, Direct Object, or Object of Preposition |
| Typical Preceding Words | Verbs (split), Auxiliary verbs (is) | Prepositions (for, of), Adjectives (gender) |
| Typical Following Words | Adjectives (important), Prepositions (among) | Verbs (is, requires), Conjunctions (and) |
| Plural Form | None (Adverbs do not have plurals) | Equalities (Rare, used in mathematics/logic) |
Tone, Context, and Formality
Both equally and equality are standard English words used across formal, academic, technical, and casual contexts. However, the domain of discussion dictates which word appears more frequently.
1. Legal, Social, and Policy Contexts
In legal framework documents, civil rights prose, policy white papers, and corporate governance guidelines, equality is the primary term. It names the broad social objective or constitutional guarantee:
- “The constitution guarantees equality under the law.”
- “Corporate diversity initiatives focus on pay equality and opportunity.”
In these settings, equally is used when specifying how rules or resources must be applied in practice:
- “All statutory provisions must apply equally to every citizen.”
2. Business, Financial, and Management Contexts
In corporate reporting, project management, and finance, equally appears frequently to describe resource allocation, risk distribution, and performance metrics:
- “Quarterly profits were distributed equally across all investment partners.”
- “Risk management responsibilities are equally shared between both departments.”
Conversely, equality appears when discussing corporate principles or mathematical balances:
- “The merger relies on an equality of voting power between both boards.”
3. Mathematics and Data Science
In technical and mathematical contexts, both terms have precise applications:
- Equality refers to the mathematical relationship where two expressions have the same value (e.g., “an equation demonstrates the equality of two sides”).
- Equally describes statistical probabilities or weighting (e.g., “all outcomes are equally likely”).
Which One Should You Use?
When writing a sentence, use these three diagnostic tests to select the correct word every time.
Diagnostic Test 1: The Part-of-Speech Test
Look at the word immediately before or after the blank space in your sentence:
- Is the target word describing or modifying an adjective (like capable, effective, valid)?$\rightarrow$ Choose equally (“equally capable”).
- Is the target word describing how an action verb (like divide, share, apply) is done?$\rightarrow$ Choose equally (“divided equally”).
- Is the target word following a preposition (like for, of, toward) or acting as the object of a verb (like demand, achieve)?$\rightarrow$ Choose equality (“strive for equality”).
Diagnostic Test 2: The Plain-English Substitution Test
Replace the word in your sentence with a simple synonym phrase:
- Can you replace the word with “to the same degree” or “in equal shares” without changing the meaning?$\rightarrow$ If yes, use equally.Example: “Both options are [to the same degree] viable.” $\rightarrow$ “Both options are equally viable.”
- Can you replace the word with “the state of fairness” or “sameness”?$\rightarrow$ If yes, use equality.Example: “We fight for [the state of fairness].” $\rightarrow$ “We fight for equality.”
Diagnostic Test 3: The Action vs. Concept Test
Ask yourself what you are describing:
- Are you describing an action being performed or a characteristic being measured? $\rightarrow$ Use equally.
- Are you naming an overarching concept, right, or legal state? $\rightarrow$ Use equality.
When One Choice Sounds Wrong
Swapping equally and equality creates noticeable grammatical errors. Examining these incorrect sentence structures will train your ear to spot and avoid errors instantly.
Error 1: Using the Noun “Equality” to Modify an Action Verb
Incorrect: “The managers decided to split the budget equality between the two teams.”
Why it fails: Split is an action verb. An action verb requires an adverb to show how the splitting was done. Equality is a noun, making the sentence structure collapse.
Correct: “The managers decided to split the budget equally between the two teams.”
Error 2: Using the Adverb “Equally” as a Direct Object
Incorrect: “Our main goal this fiscal year is to achieve workplace equally.”
Why it fails: The verb achieve requires a direct object (a noun phrase) to answer the question achieve what? An adverb like equally cannot function as a direct object.
Correct: “Our main goal this fiscal year is to achieve workplace equality.”
Error 3: The Redundant “Equally As” Construction
Incorrect: “The second candidate is equally as qualified as the first.”
Why it fails: Combining “equally” with “as… as” creates a grammatical tautology (saying “to the same degree as” twice). While common in informal speech, it is considered redundant in polished prose.
Correct: “The second candidate is equally qualified.”
Correct: “The second candidate is as qualified as the first.”

- Fix: “We ensure that opportunities are distributed equally among applicants.” (OR “We ensure opportunity equality among applicants.”)
- Typo: Incorrect hyphenation of adverbial modifiers
- Wrong: “The two tasks are equally-important.”
- Fix: “The two tasks are equally important.” (Rule: Never hyphenate an adverb ending in -ly when modifying an adjective).

Word History
equally
The word equally emerged in Middle English during the late 14th century. It was formed by taking the adjective equal (borrowed from the Latin aequalis, meaning “uniform, equal, or level”) and combining it with the native English adverbial suffix -ly (derived from Old English -lice, meaning “having the manner or appearance of”). Throughout its history, equally has consistently functioned to denote manner, degree, or uniform distribution.
equality
The word equality entered the English language in the late 14th century via Old French (égalité) and directly from the Latin noun aequalitas (“evenness, likeness, or equality”). The Latin stem aequus (“even, level, fair”) also gave English words like equity, equator, and iniquity. Historically, equality was utilized in classical rhetoric and mathematics before expanding into political philosophy during the Enlightenment to denote human rights and legal standing.
Phrases Containing
equally
- Equally important: Used to introduce a secondary point of matching significance.

FAQs
In formal writing, “equally as” is considered redundant and tautological. Phrase choices like “equally as smart as” repeat the concept of degree twice. In formal, business, or academic prose, drop “as” and use either equally alone (“equally smart”) or the paired comparative as… as (“as smart as”).
Equality is an abstract noun. The corresponding adjective form is equal (e.g., “equal rights”), and the corresponding adverb form is equally (e.g., “treated equally”).
No, adverbs cannot modify nouns directly in standard English grammar. Equally modifies verbs (“divided equally”), adjectives (“equally talented”), or other adverbs (“equally well”). To modify a noun, use the adjective equal (e.g., “equal pay”).
Equal is an adjective describing a noun (“They have equal status”).
Equally is an adverb describing an action or adjective (“They are treated equally”).
Equality is a noun naming the state or concept (“They value equality”).
Use equality whenever you need a noun to represent the concept, state, or goal of sameness or fairness. It often serves as the object of prepositions or verbs: “The constitution protects individual equality,” or “We must strive for equality in educational funding.”
No. Standard English punctuation rules state that you should never hyphenate an adverb ending in -ly when it modifies an adjective (e.g., write “an equally important decision,” not “an equally-important decision”).
Conclusion
Understanding equally vs equality comes down to recognizing the fundamental distinction between adverbs and nouns. Whenever your sentence describes how an action is performed or to what extent a quality is shared, use the adverb equally. Whenever your sentence names the concept, principle, or condition of sameness and fairness, use the noun equality.
By keeping this part-of-speech distinction in mind—and avoiding phrases like “equally as”—you can write with clarity and precision across all your professional, academic, and everyday communications.
