IPA: /ˌɪrɪˈzəluːt/
KK: /ɪrɪˈzɒlʊt/
Not able to make a decision or choose a direction; feeling uncertain about what to do.
She felt irresolute about accepting the job offer, unsure if it was the right choice for her future.
Irresolute → It is formed from "ir-" (meaning not) and "resolutus" (from Latin, meaning resolved or determined). The word describes a state of being not resolved or uncertain in decision-making.
Think of someone who is 'not' ('ir-') 'resolved' ('resolutus') — that’s why irresolute means uncertain or indecisive.
