Context determines whether the subject is you or they.

Etymology and related forms: The verb koolitada is built from the root koolita- plus the infinitive ending, and its past tense forms include koolitasin (I educated), koolitasid (you educated or they educated), koolitasite (you educated, plural), and so on.
