Он ушёл прочь.

Ушёл is the past tense, masculine singular form of the verb уйти, which means to leave, to go away, or to depart.

So in this sentence:

• он = he
• ушёл = left / went away
• прочь = away / off

Because the subject is he, the verb takes the masculine past form ушёл.

In Russian, past tense changes for gender and number.

From уйти:

• он ушёл = he left
• она ушла = she left
• оно ушло = it left
• они ушли = they left

So ушёл is used because он is masculine singular.

Прочь is an adverb meaning something like away, off, or away from here.

In Он ушёл прочь, it adds a sense of movement away, often with a slightly stronger or more expressive tone than just Он ушёл.

Compare:

• Он ушёл. = He left.
• Он ушёл прочь. = He went away / He went off / He left and went away.

In many contexts, прочь adds emphasis rather than completely changing the meaning.

Yes. Он ушёл is a complete and very natural sentence.

Adding прочь is optional and usually gives one of these effects:

• extra emphasis on going away
• a slightly more vivid or literary feel
• a sense of off he went or away he went

So Он ушёл is the plain version, while Он ушёл прочь is a bit more expressive.

This is about aspect, which is very important in Russian.

• уйти is perfective
• уходить is imperfective

Уйти focuses on the action as completed: he left, and the departure happened as a finished event.

So Он ушёл means:

• He left
• He has gone away

If you used уходил, the meaning would be different. It could suggest:

• he was leaving
• he used to leave
• he went away in a context where the process matters rather than the completed result

For a simple completed departure, ушёл is the normal choice.

It is understandable and correct, but it is a bit more expressive than the most neutral everyday phrasing.

In ordinary speech, people often simply say:

• Он ушёл
• Он ушёл отсюда = He left here / He went away from here
• Он ушёл away is not Russian, of course, but English learners sometimes expect a separate word like away every time; Russian often does not need one.

So прочь is not wrong or rare, but it can sound a little more forceful, emotional, or literary depending on context.

Not always exactly. It often matches away, but it can be stronger.

Depending on context, прочь can suggest:

• away
• off
• be gone
• out of here

For example:

• Уйди прочь! = Go away! / Get out of here!

So in Он ушёл прочь, it does mean away, but it may sound a bit stronger than a plain neutral English away.

Yes, often it can be omitted if the subject is clear from context.

Russian frequently leaves out subject pronouns when they are understood.

So both are possible:

• Он ушёл прочь.
• Ушёл прочь.

The version with он is used when you want to:

• make the subject explicit
• create contrast
• avoid ambiguity
• add a little emphasis to he

Yes, this is a normal and natural order.

Russian word order is more flexible than English, but different orders can change the emphasis.

• Он ушёл прочь. = neutral, natural
• Прочь он ушёл. = marked, unusual, more literary or emotional
• Он прочь ушёл. = less neutral, possible in poetic or stylistic language

For most learners, Он ушёл прочь is the best order to use.

Ушёл is pronounced roughly oo-SHYOL or u-SHOL, with the stress on ё.

Important points:

• ё is always stressed
• ё sounds like yo
• the stress is not on the first syllable

So:

• ушёл = u-SHOL / oo-SHYOL
• not U-shel

Also, in many printed texts, Russian often writes е instead of ё, so you may see ушел. But it is still pronounced ушёл.

Yes, the final -чь may look strange to learners.

Прочь is pronounced roughly proch', with a soft ch sound at the end. The ь does not add a separate vowel; it just shows softness.

So the whole sentence is roughly:

Он ушёл прочь
= on u-SHOL proch'

You do not pronounce the ь as a separate sound.

It can, depending on context.

Because прочь is stronger than just saying ушёл, the sentence may sound:

• more vivid
• more narrative
• slightly dramatic
• sometimes literary

For example, in a story, Он ушёл прочь can sound like He walked away or He went off, with a sense of emotional distance or finality.

Without context, though, it is simply a correct sentence meaning that he went away.
