Which word is a synonym for 'knowledgeable'?

The word 'knowledgeable' refers to possessing information, understanding, or education about a particular subject. When looking for a synonym, "informed" clearly fits this definition as it implies having knowledge or information about something. This term encapsulates the idea of being well-versed or educated in a certain area, which directly aligns with the meaning of 'knowledgeable.'

In contrast, options like 'uninformed' and 'illiterate' convey a lack of knowledge or education, clearly contrasting with the notion of being knowledgeable. 'Acquainted,' while suggesting familiarity, does not necessarily imply a deep or comprehensive understanding, which a synonym for 'knowledgeable' should convey. Therefore, 'informed' is the most appropriate synonym, as it resonates directly with the idea of having a good degree of knowledge about a certain topic or area.
