Koolitanud

Koolitanud is an Estonian past active participle derived from the verb koolitama, meaning to train or educate. It denotes that the subject has performed training or education, i.e., that someone has trained others. In usage it functions as an adjective or part of a compound verb, and it agrees with the noun in number and case.

Common uses include predicative phrases and attributive descriptions. For example: Ta on koolitanud paljusid noore sportlaseid (He has trained many young athletes). Koolitanud õpetaja (a teacher who has trained others) shows how it can modify a noun. In perfect aspect, it appears with an auxiliary, as in Ta on koolitanud palju töötajaid (He has trained many employees).

Koolitanud contrasts with koolitatud, the past passive participle, which indicates that someone or something has been trained or educated by someone else. For instance, koolitatud töötaja means a trained employee, emphasizing the outcome of training received rather than the trainer.

Related terms include koolitaja (someone who trains or educates) and koolitus (the act or process of training). Koolitanud is primarily used to express that training has been carried out by the subject, while koolitatud emphasizes the result of training received.
