ease (easy)

Short answer: easy = adjective (describes a thing); ease = noun (names a state or manner). If you describe how an action happened, use with ease or easily. If you describe a noun, use easy.

Quick answer

Use easy before a noun (an easy test). Use ease as a noun after verbs or with prepositions (finished with ease). Use easily to modify verbs.

easy (adj) - This task is easy.
ease (noun) - She completed the task with ease.
easily (adv) - She completed the task easily.

Core explanation: difference and quick checks

Easy describes difficulty or simplicity. Ease names a state, manner, or freedom from effort. If you can insert a determiner like the/their or of before the word, you probably need a noun (ease). If the word sits directly before a noun, you need an adjective (easy).

Before a noun: an easy question (correct). → not *an ease question.
After a verb: solved with ease (correct). → not *solved easy.
To modify a verb: she navigated it easily (correct). → not *she navigated it easy.

Hyphenation and spacing

Hyphenate compound modifiers that appear before a noun: easy-to-use app. Do not hyphenate when the phrase follows the noun: the app is easy to use.

Correct: an easy-to-use interface.
Correct: The interface is easy to use.
Phrase spacing: use ease of use (noun phrase) rather than ease-of-use unless you're treating it as a single compound adjective.

FAQ

Is it correct to say 'completed with easy'?

No. Use 'completed with ease' or 'completed it easily.' Easy is an adjective and cannot directly modify how an action was done.

Hyphenate when the phrase precedes and modifies a noun (an easy-to-use app). Do not hyphenate when it follows the noun (the app is easy to use).

Can I say 'He is easy to deal with'?

Yes. In that idiom, easy functions as an adjective describing the person in relation to the infinitive phrase.

What's the difference between 'easy' and 'easily'?

Easy is an adjective (describes nouns). Easily is an adverb (describes verbs). Use easily to explain how someone performed an action.
