Learn Turkish: Raporunuz orada yok. - Your report is not there.

It takes the possessive suffix for 'your' (plural or formal singular). Because rapor ends in a consonant, it needs a connecting vowel. Following 4-way vowel harmony rules, the 'o' in rapor takes a 'u', making the suffix -unuz.

Where is the word for 'your' (sizin) in this sentence?

Because the suffix -unuz on raporunuz already clearly tells us whose report it is, adding the separate pronoun sizin is optional. Turkish speakers usually leave it out unless they want to add extra emphasis.

Why is yok used here instead of değil for 'is not'?

While değil negates what something is (like 'It is not a report'), yok means 'does not exist' or 'is not present'. Because we are talking about whether the report is physically present in a location, we use yok. The Turkish sentence literally translates to 'Your report at there is non-existent.'

What is the -da doing at the end of orada?

The root is ora, which means 'that place'. The -da is the locative suffix meaning 'in', 'on', or 'at'. Together, orada means 'at that place' or simply 'there'.
