"Jeho teta, jíž bude osmdesát, špatně slyší."

Translation: His aunt, who is going to be eighty, cannot hear well.

[Paul378887]

Can someone please tell me what is wrong with this translation: “His aunt, who will be eighty, hears poorly.” It seems to me to be a literal translation and very common in English. I would have thought that “cannot hear well” would have come from the negative verb — “dobře neslyší”.

"does not hear well" is more common, but we can add some more accepted translations https://books.google.com/ngrams/graph?content=does+not+hear+well%2C+hears+poorly%2C+hears+badly&year_start=1800&year_end=2019&corpus=26&smoothing=3&direct_url=t1%3B%2Cdoes%20not%20hear%20well%3B%2Cc0%3B.t1%3B%2Chears%20poorly%3B%2Cc0%3B.t1%3B%2Chears%20badly%3B%2Cc0

"...is hard of hearing" or "... is (a bit) deaf" are possibly more common expressions.
