There are two ways to form verbs in the future tense:
Using a "helping verb" plus the imperfective infinitive:
Conjugating a perfective infinitive:
The terms imperfective and perfective refer to the distinction between 2 verbs whose actual meaning is the same, but whose focus shifts from viewing the action as process (ongoing in the past, present or future) to viewing a "limit" having been reached (in the past or future; present is precluded). Sometimes this limit is an "end" (a result) and other times it is a "beginning". For a more complete explanation of this phenomenon, consult a Russian grammar.
