In this case it refers to something (event, etc) which started xxx time ago (reasonably recently - if it were longer in the past it'd been Era iniziato xxx fa). If the sentence were referring to a person starting something it would have been (Lui) ha iniziato sei ore fa as in this case it expresses an active action. I hope I've been clear :)
I thought we had to use Essere or Avere depending on which verb came after. Are you saying that some verbs can use both depending on what is being said? How are we supposed to know when to use Essere or Avere in this case?
Very helpful. If it were "he" as I mistakenly had, then (as you state) we would have transitive verb (one that takes a direct object) and hence use avere.
Here is a lingot (if I am doing it right)
Why is not correct "It is started six hours ago" but is correct "It's started six hours ago"
"It IS started" sounds wrong to me. I worked not say that. Not sure why. Native English speaker.
what's the difference between IT'S and IT IS ???? and I put YET instead of AGO … come on DUO!
