Maşallah, şu tavşan ne kadar hızlı koşuyor; kuzenim onu görünce gülmeden edemedi.

Maşallah is a very common expression used to show admiration, pleasant surprise, or appreciation, often in a warm or culturally meaningful way. In this sentence, it adds a feeling like:

• Wow
• How impressive
• What a lovely thing to see

It is especially common when talking about something beautiful, strong, fast, cute, or admirable. It is not really part of the core grammar of the sentence; it functions more like an exclamation.

Şu is a demonstrative, meaning that or sometimes this/that one over there, depending on context.

So:

• tavşan = rabbit
• şu tavşan = that rabbit / this rabbit there

In Turkish, demonstratives are very common when the speaker wants to point something out visually or emotionally. Here, şu tavşan gives the feeling of look at that rabbit!

A rough sense of the phrase is:

• Maşallah, şu tavşan... = Wow, look at that rabbit...

Ne kadar literally means something like how much / how and is often used to express degree.

So:

• hızlı = fast
• ne kadar hızlı = how fast

In this sentence, ne kadar hızlı koşuyor means how fast it is running.

This structure is very common for exclamations:

• Ne kadar güzel! = How beautiful!
• Ne kadar zor! = How difficult!
• Ne kadar hızlı koşuyor! = How fast it runs/is running!

Even though ne kadar can also appear in questions, here it is being used in an exclamatory way.

Koşuyor is the present continuous form:

• koşmak = to run
• koşuyor = is running / runs (right now, in context)

In this sentence, the rabbit is being described as if the speaker is observing it at that moment, so koşuyor fits well.

Compare:

• koşuyor = is running
• koştu = ran
• koşar = runs / would run / habitually runs, depending on context

Because the speaker is reacting to what they see, koşuyor sounds natural.

The ending -im means my, so:

• kuzen = cousin
• kuzenim = my cousin

Turkish often uses possessive suffixes instead of separate words like my, your, his/her.

So:

• kuzenim = my cousin
• benim kuzenim = my cousin

Both are possible, but benim is often omitted unless you want extra emphasis or contrast.

Because onu is the accusative/object form of o.

• o = he / she / it / that
• onu = him / her / it / that one (as a direct object)

In the sentence:

• kuzenim onu görünce = when my cousin saw it/him/her

Since the rabbit is the thing being seen, it is the direct object, so Turkish uses onu, not o.

Görünce is not a main tense form. It is a converb form meaning when seeing, upon seeing, or once ... saw.

It comes from:

• görmek = to see
• stem: gör-
• converb ending: -ünce / -ınca / -ince / -unca depending on vowel harmony

So:

• görünce = when (someone) sees/saw

In this sentence:

• kuzenim onu görünce = when my cousin saw it

This structure is very common in Turkish:

• Eve gelince beni ara. = Call me when you get home.
• Onu görünce sevindim. = I was happy when I saw him/her/it.

The subject of görünce is understood from context; here it is kuzenim.

This is a very common Turkish pattern meaning could not help doing something.

Breakdown:

• gülmek = to laugh
• gülmeden = without laughing
• edemedi = could not do

Literally, gülmeden edemedi means something like:

• he/she could not do without laughing

Natural English:

• couldn’t help laughing

This pattern is:

verb stem + -madan/-meden + edememek

Examples:

• Ağlamadan edemedi. = She couldn’t help crying.
• Bakmadan edemiyorum. = I can’t help looking.
• Sormadan edemedim. = I couldn’t help asking.

So this is an idiomatic construction, and it is very useful to learn as a whole pattern.

Because the expression -madan/-meden edememek is a fixed grammatical pattern.

• gülmeden edemedi = couldn’t help laughing

Other forms would mean something different:

• gülmeyi would be part of another structure, not this idiom
• gülüp means laughing and..., connecting actions
• gülmeden literally means without laughing, which is exactly what this idiom uses

So you should learn -madan/-meden edememek as a unit meaning:

• cannot help doing
• be unable not to do

Turkish usually places the main verb at the end of the clause.

So in:

• kuzenim onu görünce gülmeden edemedi

the final main verb is edemedi.

Before it, you get:

• the subject: kuzenim
• the object: onu
• a time/converb phrase: görünce
• another verbal phrase: gülmeden
• then the main verb: edemedi

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

Yes, in ordinary writing, a comma or even a full stop could also work depending on style.

The semicolon here separates two closely connected ideas:

1. Maşallah, şu tavşan ne kadar hızlı koşuyor
2. kuzenim onu görünce gülmeden edemedi

It shows that the second part is closely related to the first. In Turkish punctuation, writers can choose different marks for stylistic reasons. The grammar of the Turkish itself does not depend on the semicolon.

Not necessarily. Even though ne kadar can appear in questions, here it is being used as an exclamation.

Compare:

• Bu tavşan ne kadar hızlı koşuyor? = How fast is this rabbit running? / Just how fast is this rabbit running?
• Maşallah, şu tavşan ne kadar hızlı koşuyor! = Wow, how fast that rabbit is running!

In writing, punctuation helps show whether it is a question or an exclamation. In speech, intonation also makes this clear.

Grammatically, yes. Onu can mean:

• him
• her
• it
• that one

But in this sentence, the nearest logical referent is şu tavşan, so onu is understood as the rabbit.

Turkish often relies on context for pronouns, so learners need to get used to following the most natural referent.

There are three especially useful forms here:

1. koşuyor

   • from koşmak
   • present continuous
   • is running

2. görünce

   • from görmek
   • converb
   • when seeing / when saw

3. gülmeden edemedi

   • from gülmek
     • idiomatic auxiliary pattern
   • couldn’t help laughing

If you understand those three forms, the sentence becomes much easier to unpack.

A simple way to break it down is:

1. Maşallah
   an exclamation

2. şu tavşan ne kadar hızlı koşuyor
   main observation: that rabbit is running so fast

3. kuzenim onu görünce gülmeden edemedi
   result/reaction: when my cousin saw it, he/she couldn’t help laughing

So the sentence moves like this:

• admiration
• description
• reaction

That is a very natural flow in Turkish storytelling or conversation.
