Learn Turkish: Burası tuvalet değil. - This place is not the restroom.

Burası specifically means 'this place' and acts as the subject of the sentence. Bu just means 'this' (which might imply you are pointing at an object, meaning 'this object is not a toilet'), and burada means 'in here' or 'at this place', which is used to tell where something is located rather than what the place actually is.

Where is the verb 'is' in this sentence?

In Turkish, the 'to be' verb (am/is/are) is often just a suffix attached to the end of a word. For third-person statements like 'it is' or 'this place is', there is no suffix at all! The word değil simply means 'not', and standing on its own at the end of a nominal sentence, it safely translates to 'is not'.

Why isn't there a word for 'the' before tuvalet?

Turkish doesn't have a direct equivalent to the English definite article 'the'. You simply rely on context to know if someone means 'a restroom' or 'the restroom'.

How do I pronounce the ğ in değil?

The ğ (soft g) doesn't have its own hard consonant sound. Instead, it creates a smooth transition between the vowels next to it. In the word değil, it creates a sound very similar to an English 'y', making the word sound roughly like 'dey-eel'.
