"Ma grand-mère m'en achètera plusieurs pour Noël."

Translation: My grandmother will buy me several of them for Christmas.

Any ideas why it's not Grande-Mère in French?
Mon grand-père est grand, et ma grand-mère est grande aussi.

"...several of them" is very awkward in English. "...a few of them" flows better.

[TedLandres]

It's funny, I never really thought of expressions such as "of them" or "thereof" as adverbs, but then again, I never really gave it much thought in the first place.
