Questions & Answers about Мой друг пошёл обратно в большой парк.
пошёл is the past-tense, masculine singular form of the perfective, unidirectional verb пойти (to set off on foot once). Russian verbs of motion come in aspect-direction pairs:
• идти (imperfective, unidirectional) describes an ongoing movement,
• ходить (imperfective, multidirectional) describes habitual or repeated movement,
• пойти (perfective, unidirectional) marks a single completed start.
We use пошёл here because the sentence describes a completed action in the past (“he went”).
In Russian past tense, verbs take the suffix -л plus a gender/number ending:
• masculine singular: -л → пошёл
• feminine singular: -ла → пошла
• neuter singular: -ло → пошло
• plural: -ли → пошли
Since друг is a single male, the verb is пошёл.
When you express motion toward a place with в (or на), you answer куда? (“where to?”) and use the accusative case:
• в парк = “to the park” (direction)To answer (“where?”) and describe location, you would use the prepositional: • = “in the park” (static location).
