Learn Italian: Taglio qualche pezzo di carne e mescolo bene. - I cut a few pieces of meat and mix well.

In Italian, the word qualche (some / a few) is always followed by a singular noun, even though the meaning is plural. That is why it is qualche pezzo (a few pieces). If you want to use the plural noun pezzi, you must use the word alcuni instead: alcuni pezzi.

How would I say 'I cut a few pieces of it' using the pronoun ne?

To replace di carne (of meat) with 'of it', you use the partitive pronoun ne. You place it right before the conjugated verb: Ne taglio qualche pezzo e mescolo bene (I cut a few pieces of it and mix well).

Why doesn't the sentence say io taglio and io mescolo?

Italian usually drops subject pronouns like io (I) because the verb endings already show who is doing the action. Both taglio (I cut) and mescolo (I mix) end in -o, which is the regular present tense ending for 'I'.

Why use bene instead of buono at the end of the sentence?
