Omlet hazır olunca çayı fincana dolduruyorum.

Hazır olunca means when it is ready or once it is ready.

It comes from:

• hazır = ready
• olmak = to be / to become
• olunca = when it becomes / when it is

The ending -ınca / -ince / -unca / -ünce is a common Turkish time suffix meaning when or once.

So:

• hazır olmak = to be ready
• hazır olunca = when it is ready

In this sentence, it refers to the omelet.

Because omlet is the subject of the when-clause, not the direct object.

In Turkish, the basic subject form usually has no ending:

• omlet = the omelet / omelet

If it were a definite direct object, you would often see omleti.

Compare:

• Omlet hazır olunca... = When the omelet is ready...
• Omleti yiyorum. = I am eating the omelet.

So here omlet stays in its plain form because it is the thing that becomes ready.

Because çayı is the definite direct object.

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

• çay = tea
• çayı = the tea / the tea in particular

So:

• çay dolduruyorum would sound more like I am pouring tea in a more general sense
• çayı dolduruyorum means I am pouring the tea or the specific tea

Also, the extra y is a buffer consonant. Since çay already ends in a vowel sound-like glide spelling? Actually it ends in y, so the accusative appears as çayı.

Fincana is the dative form of fincan:

• fincan = cup
• fincana = to the cup / into the cup

The dative ending -a / -e often shows direction or destination.

So çayı fincana dolduruyorum means something like:

• I am pouring the tea into the cup
• literally: I am filling the tea into the cup

The important idea is movement toward the cup.

Yes, doldurmak literally means to fill.

In a sentence like this, it suggests pouring the tea into the cup so that the cup is being filled. In natural English, we often just say pour the tea into the cup, but Turkish can use doldurmak when the idea is filling up the container.

So this sentence gives a sense like:

• When the omelet is ready, I fill the cup with tea
• or more naturally in English, When the omelet is ready, I pour the tea into the cup

Dolduruyorum is the present continuous form:

• doldur- = fill
• -uyor = present continuous
• -um = I

So dolduruyorum = I am filling / I am pouring

Turkish uses the -yor form very often, including for:

• something happening right now
• a regular action in a real-life sequence
• a vivid description of what someone does

By contrast, doldururum is more like a habitual or general statement:

• Omlet hazır olunca çayı fincana doldururum.
• When the omelet is ready, I pour the tea into the cup / I usually pour the tea into the cup.

Both are possible, but dolduruyorum feels more immediate.

Turkish often drops subject pronouns because the verb ending already shows who the subject is.

In dolduruyorum, the ending tells you the subject is I.

So:

• dolduruyorum = I am filling / I am pouring

Because of that, ben is not necessary unless you want emphasis.

Compare:

• Çayı fincana dolduruyorum. = I am pouring the tea into the cup.
• Ben çayı fincana dolduruyorum. = I am the one pouring the tea into the cup.

Because Turkish normally puts the main verb at the end.

This is one of the most important word-order patterns in Turkish.

So the sentence is arranged roughly like this:

• Omlet hazır olunca = when the omelet is ready
• çayı = the tea
• fincana = into the cup
• dolduruyorum = I am pouring/filling

A very literal English-style order would be:

• When the omelet is ready, the tea into the cup I am pouring.

That sounds strange in English, but it is perfectly normal Turkish structure.

Usually yes, but it often has a slight sense of once or as soon as too.

So olunca can mean:

• when
• once
• as soon as

depending on context.

In this sentence:

• Omlet hazır olunca...

could be understood as:

• When the omelet is ready...
• Once the omelet is ready...

All of these are close in meaning.

Yes, if you break it down literally, hazır olmak is something like to be/become ready.

But as a whole, it is simply the normal Turkish expression for to be ready.

So learners should treat it as a common set phrase:

• Hazırım. = I am ready.
• Yemek hazır. = The food is ready.
• Omlet hazır olunca... = When the omelet is ready...

So even though olmak can sometimes feel like become, the whole phrase here just means to be ready.

Yes. Turkish word order is flexible, although the verb usually stays at the end.

This sentence could be rearranged for emphasis, for example:

• Omlet hazır olunca çayı fincana dolduruyorum.
• Çayı fincana omlet hazır olunca dolduruyorum.

The first version is the most neutral and natural because it starts with the time clause: when the omelet is ready.

So Turkish allows movement, but not all orders sound equally natural in every context.

Fincan usually refers to a small cup, especially one used for Turkish coffee or tea in some contexts.

So:

• fincan = cup
• bardak = glass / drinking glass

Depending on the situation, a learner might also hear:

• çayı bardağa dolduruyorum = I am pouring the tea into the glass

So fincan is not just any random container; it suggests a cup, often a smaller one.

Yes — this sentence is a good example of how much Turkish packs into suffixes.

Here are the key ones:

• ol-unca = when it is/becomes
• çay-ı = the tea as a definite object
• fincan-a = into/to the cup
• doldur-uyor-um = I am filling/pouring

So a lot of the grammar that English expresses with separate words is shown in Turkish with endings.

That is one of the biggest differences English speakers notice when learning Turkish.
