there is a three-way aspect differentiation for verbs of motion, with two forms of imperfective, determinate and indeterminate, and one form of perfective. The two forms of imperfective can be used in all three tenses (past, present, and future), but the perfective can only be used with past and future. The indeterminate imperfective expresses habitual aspect (or motion in no single direction), while the determinate imperfective expresses progressive aspect. The difference corresponds closely to that between the English "I (regularly) go to school" and "I am going to school (now)". The three-way difference is given below for the Russian basic (unprefixed) verbs of motion. When prefixes are attached to Russian verbs of motion, they become more or less normal imperfective/perfective pairs, although the prefixes are generally attached to the indeterminate imperfective to form the prefixed imperfective and to the determinate imperfective to form the prefixed perfective. For example, prefix при- + indeterminate ходи́ть = приходи́ть; and prefix при- + determinate идти́ = прийти (to arrive (on foot)).
