Questions & Answers about Ho visto i clienti che gesticolavano molto.
Why does Italian use che gesticolavano instead of a gerund like gesticolando for "gesticulating"?
In English, we use the "-ing" form after verbs of perception (like seeing or hearing). However, Italian does not use the gerund (-ndo) for this. Instead, it uses a "pseudo-relative" clause: che followed by a conjugated verb. It essentially translates to "I saw the customers that were gesticulating."
Could I just use the infinitive and say Ho visto i clienti gesticolare?
Yes, using the infinitive after a perception verb is also perfectly correct and very common. The difference is subtle: che gesticolavano strongly emphasizes the continuous, "in-progress" nature of the action at the exact moment you saw them, while the infinitive gesticolare simply states that you witnessed the action.
Why is gesticolavano in the imperfect tense? Could I use a different past tense?
It must be in the imperfect tense because it describes an action that was ongoing in the past at the moment you witnessed it. The action of gesticulating forms the "background" to your sudden perception (ho visto). A completed tense like the passato prossimo wouldn't make sense here because you are highlighting an action in progress.
If I wanted to say "I saw them gesticulating" instead of "the customers", how would this sentence change?
