Merhaba

"ben bir türlü dogrusunu çeviremedim"

can thıs be translated as "Somehow I couldn´t translate it correctly"?

Or the meaning is different?

"Somehow I couldn´t translate it correctly"   is a good translation.

Ok. Thanks

So in this sentence "bir türlü" is a adjective describing nominalized "doğrusu"? Or it works independently as "somehow"?

Can I say simply: "Bunu bir türlü doğru çeviremedim" to mean the same thing?

doğru+u(possessive)------------------->doğrusu (the correct one (of it)) (direct: its correct one)

doğru+u(possessive)+u(accusative)---->doğrusunu (the correct one (of it)) (direct: its correct one)

Ben bir türlü doğrusunu çeviremedim. (Somehow I couldn´t translate the correct one.)

just "doğru" would be a clear adverb there.

Ben bir türlü doğru çeviremedim. (Somehow I couldn´t translate it correctly.)

The adjectives may become adverbs when they attributes the verbs.

for example:

hızlı bir araba (a fast car)

hızlı koşmak (to run fast)

açık hava (the open air)

açık bırakmak (to leave on (the light etc.))

etc.

and the same logic:

doğru cevap (the correct answer)

doğru çevirmek (to translate correctly)

No "bir türlü" is not adjective. It is zarf (adverb). Because it describes the verb.

Yeah it is the same thing. And it is more correct.

 "bir türlü " is an adverb since it qualifies the action performed/unperformed. It is failed to be performed for some reason. In other words, somehow the action was failed to happen.

- Somehow [for some reason] I could not translate it correct.[ly]

Somehow [because of something you don´t know or you can´t explain]---->  qualifies  that  ---> I failed [to translate it correct [ly].
