How do you say have a drink in Hebrew?

Answer 1

to a male: shteh (שתה)

to a female: shti (שתי)

to a group: shtu (שתו)

The above commands are "drink". If you want to say "Have a drink" in the colloquial sense of asking someone to go to a restaurant with you, i.e. "Let's have a drink", you might say "Bo nikakh beera" (בוא נקח בירה) which means "Let's take a beer".
