Out of the ones you suggested, I like:
Liat - Lol about the meaning! I don't really like L-t names (
Linnet,
Lotte,
Lita,
Leto) names though, they are always kind of dry.
Ronit - I love it! I'm actually thinking of adding it to my PNL.
(Idit is more or less fine, but too close to idiot)
Shulamit- On my PNL spelled
Shulammite.
Shulamit is much more useful, though.
Yehudit*
- I kind of prefer
Judith pronounced the French way, but
Yehudit is more light and interesting.
Reut- It's gorgeous! I like my favourite is
Ruth, but
Reut is more... honest?
I like also:
Efrat- I have been lately into Ef-Af names.
Keshet- The meaning is very precious, but I like the sound.
Livnat was some time on my PNL, but nowadays I prefer
Livna or
Liv.
Tzufit- The meaning is very pretty - I adore bird-related names!
Zivit- Much better than all the Lucy-names! :D
