"אתה בסדר?"

Translation: Are you ok?

[pauli_tics]

What about: You are alright?

[NaftaliFri1]

That's fine.

[ChromateX]

Seems like ב can be pronounced B or V; is there a rule of thumb for which one to use?

[YardenNB]

At the beginning of a word, always B. In the middle of a word, no rule of thumb...
