In Russian, most actions can be described using a pair of related verbs: a “perfective” verb and an “imperfective” verb. Though these verbs do often look and sound similar, they are used in slightly different contexts. For example:
делать[DYElat](to make, do) ← imperfective
сделать[ZDYElat](to make, do) ← perfective
зарабатывать[zaraBAtyvat](to earn) ← imperfective
заработать[zaraBOtat](to earn) ← perfective
While dictionaries usually have the imperfective verbs as the main entry, most dictionaries also provide the perfective form. Check out our post on aspect pairs in Russian to learn more!
