Movimenti is a noun, not a verb.
Was this pharse in the Verbs “grammar challenges”?
Yes, in “Subjunctive, Indicative, and Imperative”. It looks like the result of an over-eager search for verb conjugations.
But I didn’t even know about the verb “movimentare” (to enliven/animate, to liven up), so I learnt something anyhow.
Avere alone can be the verb of the sentence. It translates as “Squirrels have rapid movements.” This is somewhat clumsy and a better verb would be fare, but it’s a functioning sentence. Like all translations, the ones provided don’t always match up perfectly with the original.
