Anneannem gelince, birlikte çay içeceğiz.

Anneannem means my maternal grandmother.

It breaks down like this:

• anneanne = mother’s mother, so maternal grandmother
• -m = my

So:

• anneanne = grandmother on your mother’s side
• anneannem = my grandmother on my mother’s side

This is different from babaanne, which means paternal grandmother.

In Turkish, possession is usually shown by adding a suffix directly to the noun, not by using a separate word like my.

So instead of:

• my grandmother

Turkish uses:

• anneannem

This is very normal in Turkish:

• ev = house

• evim = my house

• annem = my mother
• dedem = my grandfather
• anneannem = my maternal grandmother

So the whole idea is packed into one word.

Gelince means when she comes, once she comes, or when my grandmother comes.

It comes from:

• gel- = come
• -ince = a suffix meaning something like when / once / upon

So:

• gelince = when coming / when she comes / once she comes

In this sentence, the subject is understood from anneannem, so anneannem gelince means when my grandmother comes.

Not exactly. -ince is not a main tense like past, present, or future. It creates an adverbial clause.

It links one action to another:

• Anneannem gelince, ... = When my grandmother comes, ...

It tells you the time or condition for the main action.

A useful way to think of it is:

• main clause = the real statement
• -ince clause = the time-setting part

Here:

• Anneannem gelince = when my grandmother comes
• birlikte çay içeceğiz = we will drink tea together

Because Turkish often does not mark future time in this kind of subordinate clause the same way English does.

English says:

• When my grandmother comes, we will drink tea

Notice that English also uses comes, not will come, after when.

Turkish works similarly here:

• Anneannem gelince = when my grandmother comes
• ... içeceğiz = we will drink

So the future meaning is clear from the whole sentence, especially from the main verb içeceğiz.

Yes, you could. Both can mean when my grandmother comes or when my grandmother arrives, depending on context.

But there is a slight difference in feel:

• gelince is very common, short, and natural for when / once she comes
• geldiğinde can sound a bit more like when she comes/arrives, at the time she comes

In many everyday situations, both work:

• Anneannem gelince, birlikte çay içeceğiz.
• Anneannem geldiğinde, birlikte çay içeceğiz.

The first one is a little lighter and more conversational.

Birlikte means together.

In this sentence:

• birlikte çay içeceğiz = we will drink tea together

Turkish word order is flexible, so birlikte can move around more than together often can in English. But the version in your sentence is very natural.

For example, you may also hear:

• Anneannem gelince birlikte çay içeceğiz.
• Anneannem gelince çayı birlikte içeceğiz.

The exact placement can change emphasis a little, but the meaning stays basically the same.

Because the verb already tells you the subject.

İçeceğiz means we will drink.

It includes:

• the verb root
• the future marker
• the we ending

So Turkish often leaves out subject pronouns when they are already clear from the verb.

Compare:

• içeceğim = I will drink
• içeceksin = you will drink
• içecek = he/she/it will drink
• içeceğiz = we will drink

You could add biz for emphasis:

• Anneannem gelince, biz birlikte çay içeceğiz.

But normally it is unnecessary.

It is built from:

• iç- = drink
• -ecek = future
• -iz / -ğiz = we

So the basic idea is:

• iç- + -ecek + -iz

This becomes içeceğiz.

A small sound change happens here: the k in -ecek softens to ğ before a vowel in the ending, which is why you get -eceğiz instead of -ecekiz.

So:

• içeceğiz = we will drink

Turkish does not use articles the way English does.

There is no direct equivalent of a/an and the in most sentences.

So:

• çay can mean tea
• depending on context, English might translate it as tea, some tea, or occasionally the tea

Here, çay içeceğiz simply means we’ll drink tea.

Also, Turkish normally keeps drink names singular in this kind of sentence:

• kahve içmek = to drink coffee
• çay içmek = to drink tea

You do not need a plural unless you specifically mean multiple teas as countable items.

Because Turkish is typically an SOV language: subject – object – verb.

In this sentence, the order is:

• Anneannem gelince = when my grandmother comes
• birlikte = together
• çay = tea
• içeceğiz = we will drink

Putting the verb at the end is very normal in Turkish.

English usually says:

• we will drink tea

Turkish usually says:

• tea we-will-drink

That is one of the most important word-order differences for English speakers.

The comma is common and helpful, especially when the time clause comes first:

• Anneannem gelince, birlikte çay içeceğiz.

It makes the sentence easier to read by separating the introductory clause from the main clause.

In less careful writing, people may leave it out:

• Anneannem gelince birlikte çay içeceğiz.

That is still understandable and often acceptable in everyday writing. So the comma is useful, but you may see both versions.

Yes. Literally, çay içmek means to drink tea.

But in natural English, the best translation is often to have tea depending on the situation.

So:

• birlikte çay içeceğiz can be understood as
  • we will drink tea together
  • we’ll have tea together

Turkish uses içmek for beverages very straightforwardly, where English sometimes prefers a more idiomatic expression like have tea.
