The prefix of the word intelligent is “in-“. A prefix is a group of letters added to the beginning of a word to modify its meaning or create a new word. In the case of intelligent, the prefix “in-” often means “in” or “not,” though its precise meaning can vary depending on the word it’s attached to. However, in intelligent, the prefix doesn’t function independently in a clear way but rather forms part of the whole word derived from the Latin intelligere, meaning “to understand” or “to comprehend.” It’s a building block of the word’s etymology.
