If U want to use as Noun, then it's YAAD. IN the use of Verb = YAAD KARNAA, KIYA, KAROONGAA / KAROONGI ETC. depending upon Subject ' Object's Gender. Keep it up.

yes right, but word order isnt right for the translation, it should be Guzre dino ki khubsurat yaad Beautiful memories of past days but this phrase would suggest something like Guzre dino khubsurat ki yaad guzare dino(past days), khoobsoorat ki yaad(memory of (something)beautiful) yes and as said earlier it means both the things, yaad may suggest - memory, recollection, remembrance, may also be used to convey same meaning as i missed u

lyly , Yaad can can be used in many ways. 1. Guzre dino khubsurat ki yaad - Memories 2. Muje Yaad aaya - I Remembered 3. Yaad karo - Try to Remember Guzre dino khubsurat ki yaad - Beautiful memories from past. :)

Here it would mean Guzre dino ki haseen yaadien or guzre dino ki khubsoorat yaadien. Good old memories of long gone days. Good memories of the past. In case Yaad teri aayi - i thought about you. haseen is basically not a hindi word but is used for poetic effect in the language.
