Ξέρουμε να δίνουμε πρώτες βοήθειες.

Ξέρουμε means we know or, in this sentence, we know how.

It comes from the verb ξέρω = to know.

Here it is in the 1st person plural:

• ξέρω = I know
• ξέρεις = you know
• ξέρει = he/she/it knows
• ξέρουμε = we know
• ξέρετε = you all / you formal know
• ξέρουν / ξέρουνε = they know

In this sentence, ξέρουμε is not just factual knowledge. With να + verb, it often means to know how to do something.

In Greek, ξέρω να + verb is a very common pattern meaning I know how to + verb.

So:

• Ξέρω να κολυμπάω = I know how to swim
• Ξέρουμε να δίνουμε πρώτες βοήθειες = We know how to give first aid

Here, να introduces the following verb phrase. English uses to in to give, but Greek uses να.

So you can think of:

• ξέρω να... = know how to...

Δίνουμε is the correct 1st person plural form of δίνω = to give.

The subject is we, so the verb also has to be we give / we are giving in form.

Why not δώσουμε?
Because Greek makes an important aspect distinction:

• δίνουμε = imperfective: giving in a general, ongoing, repeated, or skill-based sense
• δώσουμε = perfective: give once / complete the action

After ξέρουμε να, Greek usually prefers the imperfective when talking about a general ability or skill:

• Ξέρουμε να δίνουμε πρώτες βοήθειες = We know how to give first aid

That sounds natural because it refers to an ability, not one single completed act.

Because Greek often uses a main verb plus another verb after να.

Here:

• Ξέρουμε = we know
• να δίνουμε = to give / how to give

Both verbs are in forms that match the same subject, we, even though Greek does not need to say the pronoun εμείς.

So the full idea is:

• We know
  • how we would give / to give
    • first aid

This is normal Greek structure.

Because Greek is a language that often drops subject pronouns when the verb ending already makes the subject clear.

In Ξέρουμε, the ending -ουμε already tells you the subject is we.

So:

• Ξέρουμε by itself already means we know

If you add εμείς:

• Εμείς ξέρουμε να δίνουμε πρώτες βοήθειες

that gives extra emphasis, something like:

• We know how to give first aid

But in a neutral sentence, Greek usually leaves the pronoun out.

Πρώτες βοήθειες is the standard Greek expression for first aid.

Literally:

• πρώτες = first (feminine plural)
• βοήθειες = aids / forms of help (plural of βοήθεια)

So Greek uses a plural expression where English usually uses the fixed singular phrase first aid.

The adjective and noun agree:

• πρώτες matches βοήθειες
• both are feminine plural

This is just how the expression is normally said in Greek.

Because the sentence is talking about first aid in a general sense, not a specific set of first-aid measures.

So Greek naturally says:

• δίνουμε πρώτες βοήθειες = give first aid

If you added an article, it would sound more specific or less natural in this kind of general statement.

Compare the general idea:

• Ξέρουμε να δίνουμε πρώτες βοήθειες = We know how to give first aid

This is the normal way to express the skill.

Yes. Δίνω πρώτες βοήθειες is a standard and natural expression.

It literally uses δίνω = give, just like English:

• give first aid

So:

• δίνω πρώτες βοήθειες = I give first aid
• δίνουμε πρώτες βοήθειες = we give first aid

This is an expression worth learning as a whole chunk.

Yes, Greek word order is more flexible than English, but the sentence as written is the most neutral and natural:

• Ξέρουμε να δίνουμε πρώτες βοήθειες.

Because the verb endings show grammatical relationships, Greek can move words around for emphasis. But not every possible order sounds equally natural.

For a learner, the best version to remember is the original one:

• Ξέρουμε να δίνουμε πρώτες βοήθειες.

That is the straightforward, standard order.

A simple pronunciation guide is:

KSE-roo-me na THEE-noo-me PRO-tes voh-EE-thee-es

A few helpful notes:

• ξ sounds like ks
• δ in Modern Greek sounds like the th in this
• θ sounds like the th in think
• The stress falls on:
  • Ξέρουμε
  • δίνουμε
  • πρώτες
  • βοήθειες

If you say it smoothly, it sounds roughly like:

KSE-roo-me na THEE-noo-me PRO-tes voh-EE-thee-es

Specifically, it means we know how to give first aid.

That is because of the structure:

• ξέρουμε να + verb

This pattern expresses knowing how to do something.

So:

• Ξέρουμε να δίνουμε πρώτες βοήθειες = We know how to give first aid

If you just wanted to say we know first aid in the sense of being familiar with it, Greek would usually use a different wording.

Yes, but it means something slightly different.

• Ξέρουμε να δίνουμε πρώτες βοήθειες = We know how to give first aid
  
  • focuses on knowledge / skill
• Μπορούμε να δίνουμε πρώτες βοήθειες = We can give first aid
  
  • focuses more on ability / possibility

In many contexts they are close, but ξέρουμε να... is especially good when talking about having learned a skill.
