irresolute

UK /ɪˈrezəluːt/ US /ɪˈrezəˌluːt/ Syllables: ir-res-o-lute

Pronunciation
Adjective C1 Advanced Formal

Quick answer

Unable to decide or commit firmly to a course of action.

Irresolute describes a person who cannot make up their mind or stick to a decision. An irresolute leader hesitates, changes course and avoids committing. The word can also describe a reply, a manner or a look that shows doubt. Close words are indecisive, hesitant, wavering, undecided, vacillating and uncertain. The opposite is resolute, which means firm and determined. Irresolute is formal and a little critical, so it is common in descriptions of leaders and of characters in books. The adverb is irresolutely and the noun is irresoluteness. It is made from the negative prefix ir and the word resolute, so it simply means not resolute.

"He remained irresolute about whether to accept the job offer, even after the deadline passed."
