In short

A small group of Ukrainian motion verbs comes in pairs. One verb of the pair is unidirectional (односпрямоване) — one trip, one direction, happening at a definite moment: іти́, ї́хати. The other is multidirectional (різноспрямоване) — habitual, repeated, round trips, or motion in general: ходи́ти, ї́здити. English uses one word (“go”) for all of this; Ukrainian makes you choose. A second split runs across the pairs: іти́/ходи́ти = on foot, ї́хати/ї́здити = by vehicle.

The rule

Both verbs of a pair are imperfective, and both mean “to go”. The difference is the shape of the motion, not its completeness:

• Unidirectional (іти́, ї́хати) — a single journey in one direction, viewed as in progress or as one specific occasion:
  • happening now: Я йду додо́му. (I am walking home.)
  • a single planned trip: За́втра ми ї́демо у Львів. (Tomorrow we are going to Lviv.)
  • timetabled transport moving toward a goal: По́їзд іде́. (The train is coming / running.)
• Multidirectional (ходи́ти, ї́здити) — motion that is repeated, habitual, back-and-forth, or an ability:
  • a habit: Я ходжу́ до шко́ли щодня́. (I go to school every day.)
  • a completed round trip (there and back), even once: Учо́ра я ходи́в у магази́н. (Yesterday I went to the shop — and returned.)
  • a general ability: Дити́на вже хо́дить. (The child already walks.)

On top of that, pick the pair by means of travel: іти́/ходи́ти for going on foot, ї́хати/ї́здити for going by any vehicle (car, bus, train, bike). Saying іти́ в Ки́їв implies walking the whole way.

Adverbs are a reliable signal. Habit words — щодня́, ча́сто, і́ноді, за́вжди, щоро́ку — pull the multidirectional verb. Point-in-time words — за́раз, ось, тепе́р, за́втра (one planned trip) — pull the unidirectional verb.

Forms & patterns

The four core verbs, present tense. Note the stress shift in ходи́ти (ходжу́ → хо́диш):

Past tense (gender and number). іти́ has two accepted variants — the й-form after a vowel, the і-form after a pause or consonant:

The same uni/multi split runs through the other motion pairs. The я-form and the masculine past are the cells that catch people out:

In бі́гти the ж runs through the whole present (біжу́, біжи́ш, біжа́ть), while леті́ти and носи́ти change in the я-form only (лечу́, but лети́ш; ношу́, but но́сиш). біг and ніс take no -в — they are the consonant stems of lesson 25 — but бі́гла, несла́, несли́ are regular.

Examples

Common mistakes

• Я ходжу́ до шко́ли за́раз. -> Я йду до шко́ли за́раз. — a single trip happening now is unidirectional (іти́), not ходи́ти.
• Я йду до шко́ли щодня́. -> Я ходжу́ до шко́ли щодня́. — a repeated, habitual action takes multidirectional ходи́ти.
• Я йду в Ки́їв на по́їзді. -> Я ї́ду в Ки́їв на по́їзді. — travel by vehicle uses ї́хати/ї́здити, never іти́/ходи́ти.
• Ми ї́демо до мо́ря щоро́ку. -> Ми ї́здимо до мо́ря щоро́ку. — a yearly, repeated trip needs multidirectional ї́здити.
• Дити́на вже йде. -> Дити́на вже хо́дить. — the general ability to walk is multidirectional ходи́ти.
• За́раз я ходжу́ додо́му. -> За́раз я йду додо́му. — one journey in progress right now is unidirectional іти́.

Tips

• Picture one arrow (іти́, ї́хати — one trip, one way) versus many arrows / a loop (ходи́ти, ї́здити — repeated or there-and-back).
• Feet or wheels? іти́/ходи́ти = on foot; ї́хати/ї́здити = by any vehicle. Decide this before you pick uni vs multi.
• A completed round trip is multidirectional even if it happened once: Я ходи́в у теа́тр = I went to the theatre (and came home).
• Adverbs give it away: щодня́, ча́сто, за́вжди → multidirectional; за́раз, тепе́р, за́втра (a single planned trip) → unidirectional.
• Timetabled transport takes the unidirectional verb when it heads for its goal: Авто́бус іде́, по́їзд іде́.
• Address politely with ви: Куди́ ви ї́дете? Reserve ти for friends and family: Куди́ ти йдеш?
• Add a prefix (при-, ви-, за-, по-) and these roots turn perfective with new meanings — that is the next stage of motion verbs.
