Canını koru.

Koru is the informal singular imperative of korumak, which means to protect.

So this is the form you use when telling one person directly to do something:

• Koru = protect
• Koruyun = protect, said politely or to more than one person

In Turkish, the subject sen is usually omitted in commands, because it is already understood.

Canını can be broken down like this:

• can = life, soul, spirit, inner self
• -ın = your
• -ı = accusative ending, marking it as the direct object

So:

• canın = your life / your soul
• canını = your life / your soul as the thing being protected

The suffixes appear in these shapes because of vowel harmony:

• can has the vowel a, so the possessive becomes -ın
• the accusative becomes -ı

Because Turkish usually shows possession with a suffix on the noun, not with a separate word.

So instead of saying something like your life with a separate your, Turkish normally says:

• canın = your life

You can add senin for emphasis or contrast, but it is not normally needed:

• senin canın = your life, with extra emphasis

In this sentence, the suffix alone is enough.

Because it is the direct object of koru.

Turkish often marks a definite or specific direct object with the accusative. Here, the speaker is talking about a specific thing: your life / your own self.

So:

• canın = your life
• canını = your life, as the object of the verb

With verbs like korumak, this marked object is the normal pattern.

Yes. Canını can be understood in two ways:

• can-ın-ı = your life as object
• can-ı-nı = his/her life as object

These two forms end up looking the same.

Usually, context makes the meaning clear. In Canını koru, since the verb is an imperative addressed to you, the natural reading is Protect your life / Protect yourself.

If you wanted his/her life, you would often make that explicit:

• Onun canını koru = protect his/her life

Can is a very common Turkish word with a wider range than any single English word.

Depending on context, it can suggest:

• life
• soul
• spirit
• inner self
• one’s very being

In this sentence, it gives a sense like:

• protect your life
• protect your own self
• preserve your safety

So it feels a bit more intense or personal than a purely mechanical protect yourself.

Yes, absolutely.

• Kendini koru = protect yourself
• Canını koru = protect your life / protect your very self

The difference is mainly nuance:

• kendini focuses on yourself as a person
• canını focuses more on your life, safety, or very being

So Kendini koru is more straightforward and general, while Canını koru can sound more dramatic, urgent, or emotionally charged.

Because Turkish normally puts the verb at the end.

In a full sentence, Turkish often follows a subject–object–verb pattern. In an imperative, the subject is usually omitted, so object + verb is very natural:

• Canını koru

You can change word order for emphasis, but the neutral order here is the standard one.

You would say:

• Canınızı koruyun

This is the polite singular form and also the plural you form.

Breakdown:

• canınız = your life, with plural/polite your
• canınızı = your life as object
• koruyun = protect

So:

• Canını koru = protect yourself, said to one person informally
• Canınızı koruyun = protect yourself, said politely or to multiple people

Roughly like this:

• ca in can sounds like ja in jar
• Turkish c is pronounced like English j
• Turkish ı has no exact English equivalent; it is a relaxed back vowel, somewhat like the weak vowel in some unstressed syllables, but not exactly the same
• r in Turkish is usually a light tap, not a heavy English r

A rough approximation for an English speaker is:

• jah-nuh-nuh ko-roo

That is only an approximation, but it helps with the general shape.

It is understandable and natural, but its tone is a little strong or dramatic.

In everyday speech, people may also say things like:

• Kendini koru = protect yourself
• Kendine dikkat et = take care of yourself / be careful
• Dikkatli ol = be careful

So Canını koru works well, especially when the focus is on safety, danger, or survival, but it is not the only natural option.
