Halsiz olsan da su içmeden olmaz.

Halsiz means weak, drained, lacking energy, listless. It often describes the kind of weakness you might feel from illness, dehydration, hunger, or exhaustion.

So it is not just tired in the ordinary sense; it usually suggests physical weakness or low strength.

Olsan da comes from olmak (to be / to become).

Breakdown:

• ol- = be / become
• -sa / -se = conditional suffix, often if
• -n = you (second person singular)

So:

• olsan = if you are / if you were
• olsan da = even if you are / although you are

In Turkish, conditional + da/de is a very common way to express even if / although.

So:

• Halsiz olsan da = Even if you are weak

That is a very natural question.

• olsan da usually fits states or more general hypothetical situations: even if you are weak
• olursan da more strongly suggests becoming that way: even if you become weak

Since halsiz describes a condition or state, olsan da sounds more natural here.

Compare:

• Halsiz olsan da... = Even if you are weak...
• Halsiz olursan da... = Even if you become weak...

The second one is not impossible, but it shifts the meaning a bit.

It is the same word in form, but here its function is a little different.

In this sentence, da adds a concessive meaning:

• olsan da = even if you are / although you are

So here da is not simply too/also. It helps create the idea of despite that or even so.

Also, notice that this da is written separately, because it is a particle, not a suffix.

Yes, that is possible.

Because halsiz is an adjective, Turkish can express if you are weak in two ways:

• halsizsen = if you are weak
• halsiz olsan = if you are weak

So both of these can work:

• Halsizsen de...
• Halsiz olsan da...

The version with olsan da is very common and sounds quite natural in concessive structures like this. It can feel slightly more expanded or stylistically smoother.

İçmeden means without drinking.

It comes from:

• iç- = drink
• -meden / -madan = without doing

So:

• içmeden = without drinking
• yemeden = without eating
• gitmeden = without going

This form is very useful in Turkish. It links an action to the main clause and means that the main situation happens without that action being done.

So:

• su içmeden olmaz = it won’t do without drinking water / you can’t skip drinking water

Because su here is meant in a general sense: water as a substance, not the water as a specific object.

• su içmeden = without drinking water
• suyu içmeden = without drinking the water

Using the bare noun is very normal when speaking generally about eating, drinking, or using something:

• ekmek yemek = to eat bread
• kahve içmek = to drink coffee
• su içmek = to drink water

So in this sentence, su means water in general.

Yes, literally olmaz is the negative of olur from olmak, but in real Turkish it often has broader meanings like:

• it won’t work
• it’s not possible
• it’s not acceptable
• you can’t do that
• that won’t do

In the pattern -meden olmaz, it often means:

• you can’t do without ...
• ... is necessary
• you really need to ...

So:

• su içmeden olmaz does not just mean it is not without drinking water
• it idiomatically means you must drink water / you can’t go without drinking water

Yes.

The form olsan contains the second person singular ending, so it is addressing you:

• olsan = if you are / were

Turkish often leaves pronouns unstated when the verb already shows the person.

So the sentence is effectively talking to you, even though sen is not written.

If it were plural or polite you, it would be:

• Halsiz olsanız da su içmeden olmaz.

A rough breakdown is:

• Halsiz = weak / drained
• olsan da = even if you are
• su = water
• içmeden = without drinking
• olmaz = it won’t do / it’s not possible

So the structure is:

• [Even if you are weak] [without drinking water] [it won’t do].

More natural English would be something like:

• Even if you feel weak, you still need to drink water.
• Even if you’re weak, going without water is not an option.

It most naturally sounds like advice with a strong necessity meaning.

The phrase -meden olmaz often expresses something like:

• you really need to...
• you can’t skip...
• it’s necessary to...

So the tone is not just neutral description. It sounds more like:

• Even if you feel weak, you still have to drink water.

That is why olmaz here feels stronger than a simple should in English.
