Why can't it be "I hear it perfectly?" , as in "Do you hear the music?" Since 'la musica' is feminine, couldn't you answer, "La sento perfettamente." ?
"La" in this sentence is a bit confusing because in italian we usually use the third person feminine when we are formally talking to someone we don't know well, or in general as a sign of respect; so "La sento perfettamente" could also be translated as "I hear YOU perfectly" (so this translation should be accepted as right).
which is the difference between "sentire" and "ascoltare"? When to use each?
If you use i feel her perfectly would that be considered intimate, médical, neither?
the pronoun "La sento..." works with:
1) I hear her
2) I hear it (feminine noun)
3) I hear you (polite form for both gender)
"Lo sento..." = "I hear him..." or " I hear it..."(masculine noun)
"I hear You perfectly" - accepted. In my opinoin this should be the first choice for the answer. Second choice would be "I hear her perfectly", which is also correct.
I can hear her perfectly. Rejected.
In English, it is perfectly natural and normal to use "can" when talking about the senses: "Can you taste the garlic in this sauce?" "Can you see that bird?" "I can't feel my legs." "I can smell smoke." "Can you hear that music?"
