Questions & Answers about Mi sono piaciuti gli smalti, ne ho comprati parecchi.
Why do we use parecchi here instead of parecchio?
In this sentence, parecchi acts as an indefinite pronoun standing in for the noun smalti (nail polishes). Because it means "several [of them]", it must agree in gender and number with the noun it replaces, which is masculine and plural.
What is the word ne doing in the second half of the sentence?
Why does comprati end in -i when it uses the auxiliary verb avere (ho)?
Normally, past participles don't change their endings when paired with avere. However, when you use the partitive pronoun ne with a quantity like parecchi, the past participle must agree with the gender and number of the noun ne replaces. Since ne replaces smalti (masculine plural), comprato becomes comprati.
Why is the first verb sono piaciuti rather than "ho piaciuto"?
