IPA: /ʌnˈraɪp.li/
KK: /ʌnˈraɪpli/
In a way that something is not fully developed or mature, often referring to fruit or other natural products that are not ready to be eaten.
The fruit was picked unripely, so it was too sour to eat.
Unripely → It is formed from "un-" (meaning not) and "ripe" (from Old English "rīpe", meaning fully developed or matured) and the suffix "-ly" (meaning in a manner). The word "unripely" means in a manner that is not fully developed or matured.
Think of 'not' ('un-') being added to 'ripe', which means fully developed, to remember that 'unripely' describes something that is not yet mature.
