Нужно продолжить работу.

Нужно means it is necessary, it is needed, or more naturally in English, need to / must depending on context.

In this sentence, нужно is part of an impersonal construction. That means there is no explicit subject like I, you, or we. Russian often does this when the person is obvious from context or when the statement is meant more generally.

So Нужно продолжить работу literally feels like:

It is necessary to continue the work.

But in natural English it may be understood as:

• We need to continue the work
• You need to continue the work
• The work needs to continue

The exact subject depends on context.

Because after нужно, Russian usually uses the infinitive to say what needs to be done.

So the pattern is:

нужно + infinitive

Examples:

• Нужно идти. — It is necessary to go.
• Нужно работать. — It is necessary to work.
• Нужно продолжить работу. — It is necessary to continue the work.

This is very common and natural in Russian.

Because работу is the accusative case, and here it is the direct object of the verb продолжить.

The verb продолжить means to continue something, so it takes an object:

• continue what? — работу

Case forms:

• nominative: работа
• accusative: работу

So:

• работа = work, as the subject
• работу = work, as the object

Compare:

• Работа важна. — The work is important.
• Нужно продолжить работу. — It is necessary to continue the work.

This is a question of aspect.

• продолжить = perfective
• продолжать = imperfective

In this sentence, продолжить presents the action as a single necessary step: to resume / to continue on. It focuses on the fact that the action should be carried out.

Нужно продолжить работу means something like:

• We need to continue the work
• We need to get back to the work
• The work must be continued

If you say Нужно продолжать работу, that sounds more like:

• It is necessary to keep working
• We need to continue working over time

So the difference is roughly:

• продолжить работу = continue the work as a step or decision
• продолжать работу = keep continuing the work, emphasize the ongoing process

Both are possible, but they are not identical.

Yes, but it is not stated explicitly.

Russian often leaves out the person when using нужно. The sentence does not directly say who needs to continue the work. That must come from context.

Depending on the situation, it could mean:

• I need to continue the work
• You need to continue the work
• We need to continue the work
• It is necessary to continue the work

So this is one of those Russian sentences where English often wants a subject, but Russian does not need one.

Yes. Надо продолжить работу is also correct and very common.

Надо and нужно are often close in meaning:

• надо = need to, have to
• нужно = necessary, need to

In many everyday contexts they are interchangeable.

Very roughly:

• надо can sound a bit more conversational
• нужно can sound a bit more neutral or slightly more formal/bookish in some contexts

But the difference is usually small.

So both of these work:

• Нужно продолжить работу.
• Надо продолжить работу.

Yes. Russian word order is flexible, although the neutral order here is:

Нужно продолжить работу.

Other orders are possible, for example:

• Работу нужно продолжить.
• Продолжить работу нужно.

These alternatives may shift the emphasis:

• Работу нужно продолжить emphasizes the work
• Продолжить работу нужно can sound more marked or contrastive, depending on context

But for a learner, Нужно продолжить работу is the safest and most neutral version.

Usually the work in English, because it often refers to some specific work already known from context.

Russian does not have articles, so работу by itself can mean:

• work
• the work
• sometimes even a job/task, depending on context

In this sentence, English will often choose the work because the idea is usually specific:

• We need to continue the work

But in some contexts a more natural translation might be:

• We need to continue working
• We need to carry on with the work

So the best English version depends on the situation, not just the Russian grammar.

Both are possible, but they are structured differently.

• продолжить работу = continue the work
  Here, работу is a noun.

• продолжить работать = continue working
  Here, работать is a verb.

So:

• Нужно продолжить работу. — We need to continue the work.
• Нужно продолжить работать. — We need to continue working.

The meaning is similar, but the focus is slightly different:

• noun version = emphasis on the task/project
• verb version = emphasis on the activity itself

The stress is:

• Ну́жно
• продолжи́ть
• рабо́ту

A simple pronunciation guide:

NUZH-na pra-dal-ZHEET ra-BO-tu

A few notes:

• ж sounds like the s in measure
• unstressed о is reduced in pronunciation, so it often sounds closer to a than a clear English o
• ть at the end of продолжить is soft

So in connected speech, it sounds approximately like:

NUZH-na pra-dal-ZHEET ra-BO-tu

It is basically neutral.

Нужно продолжить работу could be used:

• at work
• in a meeting
• in writing
• in everyday speech

It sounds normal and standard. It is not especially slangy or especially formal.

If you wanted something more conversational, you might hear:

• Надо продолжить работу.

If you wanted something more official or bureaucratic, you might see longer constructions, such as:

• Необходимо продолжить работу. — It is necessary to continue the work.

But your original sentence is perfectly standard and natural.
