"Des pommes ? Lesquelles ?"

[Arjofocolovi]

• Singular form : masculine / feminine Lequel / laquelle = which one
• Plural form : masculine / feminine Lesquels / lesquelles = which ones
• Singular form : masculine / feminine Quel / Quelle = which
• Plural form : masculine / feminine Quels / Quelles = which

Ex : "Lequel veux-tu ?" = "Which one do you want ?" - "Je ne sais pas dans quel panier le mettre." = "I don't know in which basket I should put it."

Also, note that in an exclamation or interrogative sentence, "Quel / Quels / Quelle / Quelles" can be translated as "What / What a".

Ex : "Quelle magnifique journée !" = "What a beautiful day !" - "Quel est ce bruit ?" = "What is that noise ?"

Thank you! That was extremely helpful!

How can you tell the difference between Lesquelle, Laquelle, Lequel and Quelle?
In what situation would you use each of these?

can't be "the apples? which ones?"
some apples? doesn't make as much sense to me...

Both "Apples ? Which ones ?" and "Some apples ? Which ones ?" should be accepted.

But not "The apples ? Which ones ?", which would be translated as "Les pommes ? Lesquelles ?"
