kol tuv (כל טוב)
Wishing you the best always
You say "Hachi tov be"
اتمنى لك الافضل Atamana laka al'afdal
you need not to say it but tho opposite person will just understand you if he/she is really wishing to understand you.
I think you meant to say "the best IN the world". It is hatov ba'olam.
best of the best = הטוב ביותר (hah-TOHV beh-yo-TEHR)
The typical phrase is, "acharon, acharon chaviv" (last is the best)
You say 'Yalda' in Hebrew
yadua hatov beyoter (ידוע הטוב ביותר)
Best wishes
vontade você
It depends on what you mean by that term. If you are wishing someone an enjoyable time while crafting something, you would say tehanéh (×ª×”× ×”) to a male and tehanéh (×ª×”× ×™), which literally means "enjoy!"
