אַתָּה מֵבִין?

Stress the final syllable of each word: a-TA me-VIN.

Use אַתָּה מֵבִין? to check whether a man or boy understands something. You can also add what you are asking about, as in אַתָּה מֵבִין מָה אָמַרְתִּי? (“Do you understand what I said?”). Depending on your tone, the question can sound helpful or impatient.

אַתָּה means “you” when addressing one male, and מֵבִין is the masculine singular present form of “understand.” When addressing one female, say אַתְּ מְבִינָה? (at mevina?).
