Questions & Answers about Hayır, belge sahte değil.
- Hayır = No
- belge = document
- sahte = fake / forged
- değil = not / is not
So the structure is basically:
No, document fake not.
That sounds odd in English, but it is normal in Turkish.
In Turkish, değil is used to negate:
- nouns
- adjectives
- noun-like predicates
Here, sahte is an adjective meaning fake, so Turkish says:
- belge sahte = the document is fake
- belge sahte değil = the document is not fake
By contrast, Turkish usually uses a negative suffix with verbs:
- geliyor = he/she is coming
- gelmiyor = he/she is not coming
So değil is used because the predicate is adjectival, not a normal verb.
