Teyzem hafta sonu bize gelecek.

Teyzem breaks down as:

• teyze = maternal aunt
• -m = my

So teyzem means my aunt, specifically my mother’s sister in the basic family sense.

Turkish usually shows possession with a suffix on the noun rather than a separate word.

So instead of saying something like my aunt with a separate my, Turkish often says:

• teyzem = my aunt

You can add benim for extra emphasis:

• Benim teyzem hafta sonu bize gelecek.

But in normal speech, teyzem by itself is enough.

Turkish often uses bare time expressions without a preposition where English uses on, at, or in.

So:

• hafta sonu = on the weekend / this weekend

This is very normal in Turkish. English needs a preposition, but Turkish often does not.

Also, hafta sonu is a fixed expression meaning weekend.

Because the verb gelmek means to come, and motion toward a destination usually takes the dative case in Turkish.

• biz = we / us
• bize = to us

So:

• bize gelmek = to come to us / come to our place

Without the -e ending, biz would not fit here.

It can mean both, depending on context.

Literally:

• bize gelecek = he/she will come to us

But in natural English, this often becomes:

• she’ll come over
• she’ll come to our place
• she’ll visit us

So bize gelmek is a very common way to say someone is coming to your home or coming to see you.

Gelecek is the future tense.

It comes from:

• gel- = come
• -ecek = future tense suffix

So:

• gelecek = he/she/it will come

The future suffix appears as -ecek or -acak depending on vowel harmony. Here it is -ecek because gel- has a front vowel.

In the 3rd person singular (he/she/it), Turkish often has no extra personal ending after the tense marker.

So:

• geleceğim = I will come
• geleceksin = you will come
• gelecek = he/she/it will come

In this sentence, teyzem tells you who the subject is, so gelecek naturally means my aunt will come.

Turkish default word order is often Subject – Time – Place – Verb, with the verb at the end.

So this sentence is very natural:

• Teyzem hafta sonu bize gelecek.

But Turkish word order is flexible, and you can move parts around for emphasis. For example:

• Teyzem bize hafta sonu gelecek.
• Hafta sonu teyzem bize gelecek.

These are still understandable, but the original order is very standard and neutral.

Turkish usually does not use subject pronouns unless they are needed for emphasis or contrast.

Since teyzem already tells us who the subject is, adding o would usually be unnecessary.

So:

• Teyzem hafta sonu bize gelecek. = perfectly natural

If you said O teyzem hafta sonu bize gelecek, it would sound marked and would usually need a special reason, such as emphasis.

By itself, most people would understand it as this coming weekend or at the weekend in a specific situation.

If you wanted a more general, repeated meaning such as on weekends, Turkish would usually make that clearer through context or a different verb form, for example a habitual expression.

So in isolation, the most natural reading is:

• My aunt will come this weekend.
