how to say “good looking” in Hebrew
נָאֶה, יָפֶה
When describing the beauty of objects in Hebrew, we typically use יָפֶה

אֵיזוֹ חֻלְצָה יָפָה!

When describing people, however, the more appropriate word is נָאֶה listen and repeat for a male and נָאָה listen and repeat for a female.

Nevertheless, sometimes non-human objects are described as נָאֶה or נָאָה, as the root of the word – נ.א.ה (n.a.h) – means pleasant.
For example:
מָחָר, מֶזֶג הָאֲוִיר יִהְיֶה נָאֶה.
Tomorrow the weather will be fair.
Likewise, יָפֶה and יָפָה are often used to refer to people as well.
