Learn Turkish: Ofiste çalışmak zor değil. - Working in the office is not hard.

The suffix -mak turns the verb root çalış (work) into a noun, meaning 'working' or 'to work'. This allows the action of working to become the subject of the sentence, just like in English when we say 'Working is not hard.'

Why does ofiste end with -te instead of the usual -de for 'in' or 'at'?

The word ofis ends in an unvoiced consonant (s). In Turkish, when a suffix starting with d attaches to a word ending in a hard sound (like p, ç, t, k, s, ş, h, f), the d changes to a t to make pronunciation easier. So, instead of ofis-de, it becomes ofiste.

Is çalışmak translated as 'working' or 'to work'?

It can be both! The -mak / -mek suffix acts as both the '-ing' noun form (gerund) and the 'to do something' form (infinitive). Translating this sentence as 'To work in the office is not hard' is also completely correct.

Why isn't there a word for 'is' before değil?

In Turkish simple present statements, the 'to be' verb is often invisible for the third person. The word değil simply means 'not'. When paired with an adjective like zor (hard), zor değil automatically means 'is not hard' without needing an extra verb.
