Educated means having had a good deal of schooling. Well educated, an educated guess, educated at home.
An educated guess is one made from knowledge rather than at random, and it is the commonest use of the word by far. Applied to people it can be a class marker as much as a fact, which is worth noticing when it appears in a description.

From educate + -ed. educate comes from Middle English educaten, from educat(e) + -en, from Latin ēducātus, the perfect passive participle of ēducō (“(of a child, physically or mentally) to bring up, train, nourish; (of a person in learning or art) to rear, educate, train; (plants or animals) to nourish, support, or produce”) (see -ate), further from an intensive/frequentative formed on ēducō + -ō.
