Question

What is the difference in these structures.

1) Ho Mangiato

2) Io Mangavo

3) Avendo Mangiato.

If needed please make them in a sentence.

Thankyou, grazie

Answer 1

There is a mistake.. Io mangiavo ( inperfect tense) verb to eat (mangiare)

** 1) Yesterday I have eaten a cake ..* Ieri ho mangiato una torta**

**2)  while I was eating an ice-cream arrived a friend of mine

...." mentre mangiavo un gelato arrivò un mio amico"

** avendo mangiato is "gerundio tens"

* having eaten a lot I finished in hospital** Avendo mangiato molto finii in ospedale "
