Learn Turkish: Senin için endişelendim diye bilerek yaptım. - I did it deliberately because I was worried about you.

That is the magic of diye! When you want to say 'because', you can use a regular, fully conjugated verb (like endişelendim, meaning 'I worried') and just put diye right after it. It is an informal, everyday alternative to using için with those trickier verb endings (like endişelendiğim için).

Doesn't diye literally mean 'saying'?

Yes! It comes from the verb demek (to say). Originally, this sentence structure meant something literally like 'Thinking or saying I am worried about you, I did it knowingly.' In modern, everyday Turkish, this has evolved into a standard, casual way to express 'because'.

Why do we use Senin için here if it translates to 'about you' rather than 'for you'?

The word için is most commonly known as 'for', but it is also used to mean 'about' with verbs of emotion, like endişelenmek (to worry). Remember that personal pronouns like sen must take the genitive case (becoming senin) when followed by a postposition like için.

How exactly does bilerek translate to 'deliberately'?

It comes from the verb bilmek (to know) combined with the -erek suffix, which means 'by doing' or 'while doing'. So, bilerek literally translates to 'by knowing' or 'knowingly', which is the natural way to say 'deliberately' or 'on purpose' in Turkish.
