Συνεργαζόμαστε πολύ καλά.

Συνεργαζόμαστε is the verb, and it means we cooperate / we collaborate / we work together.

It already includes the subject we, so Greek does not need a separate word for we unless you want emphasis:

• Συνεργαζόμαστε πολύ καλά. = We work together very well.
• Εμείς συνεργαζόμαστε πολύ καλά. = We work together very well. (emphatic)

The ending -όμαστε is a very common 1st person plural ending in Modern Greek for verbs in the middle/passive form.

So:

• συνεργάζομαι = I cooperate / I collaborate
• συνεργαζόμαστε = we cooperate / we collaborate

Even though this looks like a passive-type ending, here the meaning is not passive in English. It does not mean we are collaborated. It is just the normal form this verb uses.

Grammatically, it uses middle/passive endings, but in meaning it is usually active.

So:

• συνεργάζομαι με κάποιον = I collaborate with someone

This is very common in Greek: some verbs appear in these endings but are translated with an active verb in English.

Usually, no.

Greek often leaves out subject pronouns because the verb ending already shows the person and number.
Since -όμαστε clearly means we, εμείς is optional.

You add εμείς only if you want contrast or emphasis:

• Εμείς συνεργαζόμαστε πολύ καλά, αλλά αυτοί όχι.
  = We work very well together, but they do not.

In this sentence:

• πολύ = very
• καλά = well

Together, πολύ καλά means very well.

So the structure is:

• Συνεργαζόμαστε = we work together / we cooperate
• πολύ καλά = very well

Because here you need an adverb, not an adjective.

• καλός, καλή, καλό = good
• καλά = well

The sentence describes how we cooperate, so Greek uses the adverb:

• Συνεργαζόμαστε πολύ καλά. = We cooperate very well.

Compare:

• Είναι καλός συνεργάτης. = He is a good partner/collaborator.
  (καλός = adjective)
• Συνεργάζεται καλά. = He works well with others.
  (καλά = adverb)

Yes, Greek word order is more flexible than English, although some versions sound more natural than others.

The neutral, natural order is:

• Συνεργαζόμαστε πολύ καλά.

You may also hear:

• Πολύ καλά συνεργαζόμαστε.

That can sound more marked, as if emphasizing how well.

A learner should usually stick with:

• Συνεργαζόμαστε πολύ καλά.

Yes. The Greek present tense often covers both:

• a general/habitual meaning: we cooperate
• a current/ongoing meaning: we are cooperating

The exact meaning depends on context.

For example:

• Συνεργαζόμαστε χρόνια. = We’ve been working together for years.
• Αυτή την περίοδο συνεργαζόμαστε σε ένα νέο έργο. = At the moment we are collaborating on a new project.

It can be used in several contexts.

Συνεργάζομαι often suggests:

• working together professionally
• collaborating on a project
• cooperating with another person or group

So Συνεργαζόμαστε πολύ καλά could describe:

• coworkers
• business partners
• students on a project
• even two people who cooperate smoothly in general

If you want a more basic everyday idea of we work together, Greek might also use other expressions depending on context, but συνεργαζόμαστε is very natural.

No.

English often says work together, but Greek does not need μαζί here because the idea of cooperation is already built into συνεργαζόμαστε.

So:

• Συνεργαζόμαστε πολύ καλά. = We work together very well.

You can sometimes add μαζί for extra emphasis:

• Συνεργαζόμαστε πολύ καλά μαζί.

But in many cases it sounds unnecessary, because συνεργάζομαι already implies doing something jointly.

A simple pronunciation guide is:

see-ner-ga-ZO-ma-ste po-LEE ka-LA

A more accurate approximation:

• Συνεργαζόμαστε ≈ sinerga-ZO-maste
• πολύ ≈ po-LEE
• καλά ≈ ka-LA

Stress falls where the accent marks are:

• συνεργαζόμαστε
• πολύ
• καλά

A few sound notes:

• γ before α here sounds like a soft voiced sound, somewhat like gh
• συ sounds like si in Modern Greek pronunciation
• ου would sound like oo, but there is no ου in this sentence

The dictionary form is συνεργάζομαι.

That is the 1st person singular present form, literally I cooperate / I collaborate.

Many Greek dictionaries list verbs this way, even if in English we think of the bare form as to cooperate.

So:

• dictionary form: συνεργάζομαι
• sentence form: συνεργαζόμαστε

It is neutral and natural in both spoken and written Greek.

It works well in:

• everyday conversation
• workplace contexts
• emails
• presentations

It is neither slangy nor overly formal, so it is a very useful sentence pattern to know.
