What is the Hebrew translation for good luck?

Although many people literally translate "Mazel Tov" as "Good luck," its more accurate translation is "Congratulations." Such as we are soon to be married you say "Mazel Tov".

However, the other way of saying "Good luck" -- which is literally "To your success" -- is "B'HATZlacha."בהצלחה

And... b'HATZlacha on leaning Hebrew.

Correction:

Mazel tov literally translates as 'good luck', but it is used to mean 'congratulations'.

Tov = good

Mazel = luck
