Annem kahvaltıdan sonra iki kayısı yedi ve çok beğendi.

Because anne means mother, and the ending -m is the 1st person singular possessive suffix.

• anne = mother
• annem = my mother

This is very common with family words in Turkish:

• babam = my father
• ablam = my older sister
• dedem = my grandfather

This is a very common Turkish time expression.

• kahvaltı = breakfast
• -dan = the ablative ending, often meaning from
• sonra = after

So:

• kahvaltıdan sonra = after breakfast

Turkish uses the pattern:

noun + ablative + sonra

Examples:

• işten sonra = after work
• okuldan sonra = after school

Because of vowel harmony and normal suffix shape.

The ablative suffix has four common forms:

• -dan
• -den
• -tan
• -ten

Which one you use depends on:

1. the last vowel of the word
2. whether the last consonant is voiced or voiceless

Here:

• kahvaltı ends in the vowel ı, so the suffix uses a back vowel: a
• the word ends in a vowel, so the suffix begins with d, not t

So:

• kahvaltı + dan → kahvaltıdan

Because in Turkish, after a number, the noun is usually singular, not plural.

So:

• iki kayısı = two apricots
• üç kitap = three books
• beş öğrenci = five students

This is different from English, where we normally use the plural after numbers.

Because the direct object here is indefinite / non-specific, so Turkish often leaves off the accusative ending.

• iki kayısı yedi = she ate two apricots
  (some two apricots, not specially identified)

If you say:

• iki kayısıyı yedi

that sounds more like:

• she ate the two apricots
• she ate those specific two apricots

So the version in the sentence is very natural for a plain statement.

Yes, yedi can mean either:

• seven
• ate (past tense of yemek, to eat)

Context tells you which one it is.

In this sentence, iki kayısı yedi clearly means:

• ate two apricots

because it follows an object and fits the sentence structure of a verb.

Both are in the simple past tense with the suffix often written as -DI in grammar explanations.

• ye- = eat

• yedi = ate

• beğen- = like / find pleasing
• beğendi = liked

This tense is used for completed actions in the past.

Because Turkish often drops pronouns when the subject is already clear.

So:

• Annem ... yedi ve çok beğendi.

literally includes only one explicit subject:

• annem = my mother

The second clause keeps the same subject automatically:

• and (she) liked it/them very much

Turkish does this all the time.

Beğenmek means something like:

• to like
• to find pleasing
• to approve of
• to enjoy

In this sentence, çok beğendi most naturally means:

• she liked them a lot
• she liked it very much

With food, beğenmek often means that someone found the taste good or was pleased with it.

The object is understood from context, so Turkish leaves it out.

The most natural interpretation is:

• she ate two apricots and liked them a lot

If you wanted to say it explicitly, you could say:

• Annem kahvaltıdan sonra iki kayısı yedi ve onları çok beğendi.

Here:

• onları = them

But in Turkish, leaving it out is completely normal when it is obvious.

Both can relate to liking, but they are not exactly the same.

• sevmek = to like/love in a broader, more general sense
• beğenmek = to find something pleasing, good, satisfactory, enjoyable

For something you have just tried, tasted, seen, or evaluated, beğenmek is often the better choice.

So after eating apricots, çok beğendi sounds very natural.

Because Turkish usually prefers verb-final word order.

This sentence is structured like:

• Annem = subject
• kahvaltıdan sonra = time expression
• iki kayısı = object
• yedi = verb
• ve çok beğendi = and liked it/them a lot

So Turkish often looks like:

Subject + time + object + verb

whereas English often puts the verb earlier:

• My mother ate two apricots after breakfast and liked them a lot.

The letter ğ in Turkish is called yumuşak g (soft g), and it usually is not pronounced like a hard English g.

In beğendi, it typically does one of these things:

• lengthens the preceding vowel a little
• creates a very slight glide
• may sound almost as if there is no consonant there

So beğendi is often pronounced roughly like:

• bee-endi or
• be-yendi very lightly, depending on accent

The important thing is: do not pronounce it like the g in go.
