"A mia figlia piacciono le mele."

[ShikiHana]

My daughter is a singular third person, shoudn't "piace" be used instead?

[withanie]

technically you're saying "to my daughter, apples are pleasing," so the apples (they) are the ones that are actively doing the pleasing of your daughter, and therefore it's third-person plural.

[f.formica]

The subject of the sentence is "le mele" (note the preposition "a" in "a mia figlia").

[Pogodragon]

Did this construction just start appearing without explanation? I missed it before now anyway. Thank you for clarifying!

[Barbiequed]

withanie your explanation is perfect - very helpful

[trasteverino]

Why is it "A" mia figlia? Why not "La" or just "Mia figlia piacciono"?

[withanie]

"A" means "to". "To my daughter, apples are pleasing."

[Pete975877]

Can this also translate as 'My daughter likes apples'? If not how would you generalise this sentence?

[f.formica]

Yes, it can mean that, and that's normally the meaning without context.

[Bill98991]

Could you remove the "le" before "mele".
A mia figlia piacciono le mele. My daughter likes the (specific) apples.
A mia figlia piacciono mele. My daughter likes (generally) apples.

[f.formica]

General concepts don't need an article in English, but they do in Italian, so no, you can't remove the "le" before "mele".

[Ampus_Questor]

To say that your daughter likes apples in general, wouldn't that be expressed as "a mia figlia piacciono delle mele", ie using the partitive article, as it would be used in French? Wouldn't "le" be reserved for the specific apples that are on the table, say?
