How to use

The verb 'usiłować' (to try / attempt / endeavor / strive) is imperfective; it does not have a common perfective pair (sometimes 'spróbować' or 'pokusić się' is used). It conjugates regularly ending in '-uję' (e.g., 'usiłuję', 'usiłujesz'). It is followed by an infinitive (e.g., 'usiłować pomóc' — to try/attempt to help) and implies making a persistent effort.
