"My sister is very shrewish."

Translation: Chị của tôi rất đanh đá.

[BettinaMcNeil]

Is 'shrewish' a term we really need to know in Vietnamese? It's a little outdated and sexist and not used very often in English.

[jRsX10]

'Đanh đá' is used very often in VNese. It is not sexist at all. Maybe 'schrewish' is not the best word for it

[wordgeek416]

Bad-tempered or unpleasant would be better translations.

[JanetHoski1]

This is useful. But when I looked it up on Google Translate they said "shrewd", which is actually a good quality. What you are describing sounds like what we might call someone who is "difficult".

Google might sometimes be convenient but not always accurate.
