Learn Turkish: Et yediği halde kas kaybediyor. - Even though he eats meat, he is losing muscle.

The structure uses the verb root ye- (eat) plus the suffix -dik (which softens to -diğ- here), followed by the possessive ending -i (his/her), and finally the word halde (in the state). Literally, it means "in the state of his eating". This formula (verb + -dik + possessive + halde) is the standard way to say "even though" or "despite" a state or action.

Does yediği halde specify when he eats meat?

No, the -dik suffix doesn't strictly show tense. The time frame is understood from the main verb at the end of the sentence (kaybediyor - he is currently losing). Because of this, we understand the meat-eating as a general habit or ongoing action.

Why is the verb kaybediyor instead of "kayıp ediyor"?

Kaybediyor is a compound verb made from kayıp (loss) and etmek (to do/make). When combined, the second vowel in kayıp drops out, and the p softens to a b because it is followed by a vowel. As a bonus, the t in etmek also softens to d before the -iyor suffix!

Why don't et (meat) and kas (muscle) have the accusative case ending?
