Irresolute is an adjective that means uncertain.
The Latin word resolvere (ray sol VAIR ay) means resolved. From this we get resolute, meaning ‘determined’ and ‘unwavering.’ Our word of the day is the opposite. A person who is irresolute is wavering and undetermined.
With so many offers from colleges, it’s not surprising that Michelle is irresolute. The last time I checked she still hasn’t made up her mind.
