Questions & Answers about Eskisine kıyasla duruşun çok daha iyi görünüyor.
Why is it eskisine instead of just eskiye?
While eskiye literally means "to the old", Turkish naturally prefers using a possessive form here. The -si suffix makes it a pronoun meaning "its old version" or "the old one" (referring implicitly to your old posture). We then add the buffer -n- and the dative -e because the postposition kıyasla always requires the dative case.
Could I use oranla instead of kıyasla in this sentence?
Yes! Both eskisine kıyasla and eskisine oranla mean "compared to before" and both require the preceding word to take the dative case. Kıyasla comes from a word meaning "comparison," while oranla comes from a word meaning "ratio" or "proportion," but they are completely interchangeable in this context.
How is the word duruşun (your posture) built?
It comes from the verb durmak (to stand). The -uş suffix creates a verbal noun that describes the manner or way of doing the action, so duruş literally means "way of standing". The final -un is the possessive suffix making it "your posture".
Why does "looks" translate to görünüyor instead of a form of bakmak?
