Kind of depends on the context, but 'Nifla' is one way to say lovely in Hebrew. Another way is to just say that something is "Ya-feh"
lovely prince = nasich yafeh (× ×¡×™×š יפה)
you would simply say laila tov (לילה טוב)
nesi'ah tovah (× ×¡×™×¢×” טובה)
lovely
lovely restaurant - chamant resturante
nashim yafot (× ×©×™× יפות)
It is original Hebrew and means favour or grace but also lovely.
chimidun is not a Hebrew word, but it looks like it could be related to the word khamud (cute) or khemed (lovely). Both words are originally from Hebrew.
You say 'Yalda' in Hebrew
A lovely girl = une fille charmante.
Meu (My) amado (lovely) amigo (friend).
lovely-素敵な cat-猫
