English Translation
She could play the piano.
Perche no, lei POTEVA suonare il pianoforte?
She could play the piano.
Perche no, lei POTEVA suonare il pianoforte?
Welcome! I would have translated the phrase as “She knew how to play the piano” meaning she was able to play or she could play. Sapere is generally used here, correct elegant Italian. Happy learning!
