Ablam da üşütmüş olmalı, çünkü sabahtan beri hapşırıp duruyor ve ıhlamur istiyor.

Ablam means my older sister.

It is built like this:

• abla = older sister
• -m = my

So:

• abla = older sister
• ablam = my older sister

In Turkish, family words very often take a possessive ending like this. You can also say benim ablam, but Turkish often drops benim when it is already clear.

Here da means too / also / as well.

So Ablam da means something like:

• My sister too
• My sister as well

It often suggests that someone else may also have caught a cold, and now the speaker is adding the sister to that group.

A useful point: this da/de is written separately from the word before it.

• ablam da = correct
• ablamda = wrong in this sentence

Because these are different verbs:

• üşümek = to feel cold
• üşütmek = to catch cold / get chilled / come down with a cold

So:

• Üşümüş would mean she felt cold
• Üşütmüş means she has apparently caught a cold

In this sentence, the meaning is about being ill, not just feeling cold for a moment, so üşütmüş is the natural choice.

This is a very common Turkish pattern for making a deduction.

It breaks down like this:

• üşütmüş = apparently/it seems she caught a cold
• olmalı = must be / must have

Together, üşütmüş olmalı means:

• she must have caught a cold
• she has probably caught a cold

It shows that the speaker is inferring this from evidence, not stating it as a confirmed fact.

In many contexts, -miş can mark:

• hearsay
• indirect knowledge
• inference from evidence
• surprise/discovery

In this sentence, it is mainly the inference use.

The speaker sees clues:

• she has been sneezing
• she wants ıhlamur

So the speaker concludes: Ablam da üşütmüş olmalı.

Üşütmüş alone could already suggest indirect knowledge or inference, but olmalı makes the deduction stronger and clearer.

Compare:

• Ablam üşütmüş.
  = My sister apparently caught a cold / I gather she caught a cold.

• Ablam üşütmüş olmalı.
  = My sister must have caught a cold / She has probably caught a cold.

So olmalı adds the idea of logical conclusion.

Sabahtan beri means:

• since this morning
• all morning / ever since morning

It uses the pattern:

• X-den beri = since X

So:

• sabah = morning
• sabahtan beri = since morning

The -tan part is the ablative ending, which often gives a from idea. In this expression, it marks the starting point in time.

Hapşırıp duruyor means she keeps sneezing.

It is stronger than just hapşırıyor.

Breakdown:

• hapşırmak = to sneeze
• hapşırıp = sneezing and...
• duruyor = literally is standing, but in this kind of structure it helps express repeated or ongoing action

So:

• hapşırıyor = she is sneezing
• hapşırıp duruyor = she keeps sneezing / she goes on sneezing

This pattern often gives a sense of something continuing repeatedly.

The -ıp / -ip / -up / -üp form links verbs together. It is often called a converb.

In this sentence, it connects hapşırmak to durmak:

• hapşırıp duruyor

This is not just two separate actions. Together they form a kind of verbal expression meaning:

• to keep sneezing
• to go on sneezing

So here -ıp helps build the continuous/repetitive meaning.

Because Turkish often leaves out subjects when they are already clear from context.

The subject is still ablam throughout:

• Ablam da üşütmüş olmalı
• çünkü [ablam] sabahtan beri hapşırıp duruyor ve [ablam] ıhlamur istiyor

English usually repeats subjects more often. Turkish often does not.

It can suggest either, depending on context.

• istemek = to want
• istiyor = wants / is wanting / is asking for

Here ıhlamur istiyor most naturally means something like:

• she wants linden tea
• she is asking for linden tea

Turkish present continuous forms like istiyor are often used for present situations in a way that sounds perfectly natural.

Ihlamur is linden tea (also called lime blossom tea in British English, though it is not related to the citrus fruit).

In Turkish culture, it is strongly associated with:

• colds
• sore throats
• winter illness
• home remedies

So in this sentence, ıhlamur istiyor is another clue supporting the idea that she has caught a cold.

Yes, it is very natural.

Turkish often puts the main verb near the end of the clause:

• Ablam da üşütmüş olmalı
• çünkü sabahtan beri hapşırıp duruyor ve ıhlamur istiyor

This sentence is structured very naturally as:

1. conclusion
2. reason

So it works like:

• My sister too must have caught a cold, because...

That order is completely normal in Turkish.

Yes, a little.

Depending on tone and context, -miş olmalı can range between:

• must have
• has probably
• seems to have

So the sentence often carries a sense of strong probability based on evidence, rather than absolute certainty.

That is why translations such as these can all fit:

• My sister must have caught a cold
• My sister has probably caught a cold
• It seems my sister has caught a cold too
