Si no guanyem, encara podem empatar la partida.

In Catalan, after si meaning if, you normally use the present indicative for a real or possible future condition.

So:

• Si no guanyem... = If we don’t win...

Even though it refers to the future in English, Catalan does not usually use the future tense here.

This is very common in Catalan:

• Si plou, no sortirem. = If it rains, we won’t go out.
• Si vens, t’ajudo. = If you come, I’ll help you.

So guanyem is the normal form here.

Yes, podem is present tense, but in Catalan the present tense is often used to talk about a future possibility, especially when the situation is clear from context.

So:

• encara podem empatar la partida = we can still draw the game

This can naturally refer to what is still possible from now on.

You could also hear:

• Si no guanyem, encara podrem empatar la partida.

That is also grammatical, and it sounds a bit more explicitly future-oriented.

Very roughly:

• podem = more immediate, more natural in everyday speech in many contexts
• podrem = more clearly future

Both are possible, but podem sounds very normal here.

Here encara means still.

So:

• encara podem = we can still

It shows that the opportunity has not disappeared yet.

Compare:

• Encara hi som a temps. = We still have time.
• Encara no ha arribat. = He/She hasn’t arrived yet.

A useful distinction:

• encara = still
• encara no = not yet

So in your sentence, encara means the match/game is not lost completely; a draw is still possible.

Empatar means to draw, to tie, or to finish level.

Examples:

• Hem empatat. = We drew / We tied.
• Van empatar a dos. = They drew 2–2.

In your sentence:

• empatar la partida = to draw the game

This contrasts with:

• guanyar = to win
• perdre = to lose
• empatar = to draw / tie

So the sentence means that even if victory is impossible, a tied result may still be possible.

Catalan often uses the definite article where English may or may not use one.

Here la partida means the game / the match, referring to a specific game already understood from context.

So:

• empatar la partida = draw the game

The article sounds natural because we are talking about a particular contest.

Also, partida is often used for a game, especially in board games, cards, chess, and similar contexts.

Depending on context, Catalan might also use:

• el partit for a sports match
• la partida for a game, round, or match in a game setting

So the noun choice depends a bit on what kind of contest is being discussed.

Catalan often leaves out subject pronouns because the verb ending already shows the subject.

Here:

• guanyem = we win
• podem = we can

The ending -em tells you the subject is nosaltres (we).

So Catalan does not need to say nosaltres unless it wants emphasis or contrast.

For example:

• Si no guanyem... = If we don’t win...
• Si nosaltres no guanyem... = If we don’t win... but with extra emphasis on we

This is normal in Catalan and other Romance languages.

In Catalan, the basic way to make a sentence negative is to put no before the verb.

So:

• guanyem = we win
• no guanyem = we do not win / we don’t win

That is the standard pattern:

• No puc venir. = I can’t come.
• No ho sé. = I don’t know.

So si no guanyem literally follows the normal Catalan negative structure: if not we-win.

It is understandable, but encara podem is the more natural order.

In Catalan, adverbs like encara often go before the conjugated verb:

• encara podem
• encara tenim temps
• encara hi viu

So the most natural version is:

• Si no guanyem, encara podem empatar la partida.

Putting encara after the verb is sometimes possible in certain contexts, but here it sounds less standard and less natural.

Here it is two words:

• si = if
• no = not

So:

• si no guanyem = if we don’t win

Do not confuse this with sinó, written as one word, which usually means but rather / except.

Compare:

• Si no guanyem, encara podem empatar. = If we don’t win, we can still draw.
• No volem guanyar, sinó empatar. = We don’t want to win, but rather to draw.

This is a very common spelling point for learners.

Sometimes yes, but they are not always interchangeable.

• partit is very common for a sports match
• partida is common for a game, especially chess, cards, board games, or a round/session of play

So:

• empatar el partit = draw the match
• empatar la partida = draw the game

Your sentence sounds especially natural if the context is something like chess, cards, or another game rather than a football match.

Yes:

• Si no guanyem, encara podem empatar la partida.
• Si nosaltres no guanyem, encara podem empatar la partida.

Both are grammatical.

But Catalan usually prefers the version without nosaltres, because the verb endings already make the subject clear.

You would add nosaltres mainly for:

• emphasis
• contrast
• clarification

For example:

• Si nosaltres no guanyem, ells sí que guanyaran.
  = If we don’t win, they will.

So in your original sentence, leaving out the pronoun is the most natural choice.
