Annem misafirleri güler yüzle karşılıyor.

Annem means my mother.

It is built from:

• anne = mother
• -m = my

So:

• anne = mother
• annem = my mother

This is a very common Turkish possessive pattern:

• ev = house
• evim = my house

With anne, the form becomes annem, not annemim or anything longer.

Here misafirleri is most naturally the definite direct object: the guests.

Turkish often marks a specific/direct object with the accusative ending. So:

• misafirler = guests
• misafirleri = the guests / specific guests

That -i is the accusative ending here.

So the sentence is talking about particular guests, not just guests in general.

A learner should also know that misafirleri can sometimes be ambiguous in isolation, because it could also mean his/her guests or their guests in other contexts. But in this sentence, the most likely reading is simply the guests as the direct object.

The verb karşılamak means to greet / welcome / meet and it normally takes a direct object.

When that object is specific or definite, Turkish usually marks it with the accusative.

So compare:

• Misafirler karşılıyor. = He/She is greeting guests.
  (more general, less specific)
• Misafirleri karşılıyor. = He/She is greeting the guests.
  (specific guests)

In your sentence, the guests are understood as specific, so misafirleri is natural.

Literally, it is something like with a smiling face.

It comes from:

• güler yüz = smiling face / cheerful expression
• -le = with

So:

• güler yüzle = with a smiling face / in a friendly way

In natural English, it often means:

• warmly
• with a smile
• in a friendly manner

This is a common Turkish expression. You can also see the related adjective:

• güler yüzlü = cheerful, smiling, friendly-faced

-le / -la is the suffix meaning with.

Examples:

• arabayla = with/by car
• bıçakla = with a knife
• güler yüzle = with a smiling face

Which form appears depends on vowel harmony:

• -la
• -le

Here it is -le because it fits the vowels in yüz.

Karşılıyor is the 3rd person singular present continuous form: he/she/it is welcoming.

Breakdown:

• karşıla- = verb stem from karşılamak
• -ıyor = present continuous ending
• zero ending for he/she/it

So:

• ben karşılıyorum = I am welcoming
• sen karşılıyorsun = you are welcoming
• o karşılıyor = he/she is welcoming

Because the subject is annem (my mother), which is 3rd person singular, the verb is karşılıyor.

The dictionary form is karşılamak.

This is the infinitive, meaning to greet, to welcome, or sometimes to meet/receive depending on context.

The form changes like this:

• karşılamak = to welcome
• remove -mak
• add present continuous: karşılıyor

This happens because Turkish verbs are usually listed in dictionaries with -mak / -mek.

This is because of how the Turkish present continuous suffix works.

The present continuous suffix is basically:

• -ıyor / -iyor / -uyor / -üyor

When a verb stem ends in a vowel, that vowel often drops before this suffix.

So:

• karşıla-
  • -ıyor
• becomes karşılıyor

Not karşılayor.

You see the same pattern in many verbs:

• başla- → başlıyor = is starting
• anla- → anlıyor = is understanding

Turkish word order is flexible, but the most neutral pattern is often:

Subject + Object + Adverbial phrase + Verb

So here:

• Annem = subject
• misafirleri = object
• güler yüzle = manner phrase
• karşılıyor = verb

Since Turkish normally puts the verb at the end, this order sounds very natural.

English speakers often expect something like My mother is welcoming the guests warmly, but Turkish usually saves the verb for last.

Yes. Turkish allows some movement for emphasis.

For example:

• Annem misafirleri güler yüzle karşılıyor.
• Annem güler yüzle misafirleri karşılıyor.

Both are possible.

The version you were given is very natural. Moving parts around can slightly change emphasis, but the core meaning stays the same.

In güler, there is actually no ğ. It is spelled with a normal g:

• güler

This g is pronounced normally.

But learners often ask because Turkish has both g and ğ. They are different letters:

• g = regular hard g
• ğ = soft g, which usually lengthens or smooths the surrounding vowels rather than making a strong consonant sound

So in this sentence:

• güler has a normal g
• karşılıyor has a normal g? Actually no, it has no g at all
• yüzle also has no ğ

It is both understandable word by word and also a fixed expression.

Word by word:

• güler = smiling / that smiles
• yüz = face

So güler yüz literally means smiling face.

But in real Turkish, it is also a common set phrase meaning friendliness, warmth, a pleasant expression, or cheerful politeness.

So when you see güler yüzle, it is best to understand it as a natural expression meaning something like:

• with a smile
• warmly
• in a friendly way

Yes, depending on context, the Turkish present continuous can sometimes sound broader than the English is greeting.

Grammatically, karşılıyor is the present continuous, so the most direct translation is:

• is greeting
• is welcoming

But in some contexts, Turkish present continuous can also describe a regular or current habit more naturally than English would.

So it could mean:

• My mother is welcoming the guests
  or, in the right context,
• My mother welcomes the guests

Still, if there is no extra context, is welcoming is usually the safest first translation.
