Merhaba.

It is a well-known fact that in Turkish many of the reflexive verbs are created the same way as thew passive voice (by adding -il- or -n-) suffix. So, then.. how can you tell the difference if a verb in a sentence is meant to be reflexive or passive? Of course there are some obvious cases, like kitap yazıldı - certainly the book didn´t write itself, so it was written. BUT for example: çocuk yıkanıyor - how can you know if the child is washing themselves (having a bath) or perhaps a parent is washing them?

You should make a guess
