every [Brit ˈɛvri, Am ˈɛvri]DETEvery is usually used in front of a singular countable noun: every student = ogni studente. When every precedes a plural countable noun, it means that something happens at regular periods of time, after a certain distance, etc.: he smokes a cigarette every two hours = fuma una sigaretta ogni due ore; you'll have to fill up with petrol every 450 miles = dovrai fare il pieno di benzina ogni 450 miglia. - Every is most frequently translated by tutti/tutte + plural noun: every day = tutti i giorni. When every is emphasized to mean every single, it can also be translated by ogni o ciascuno. For examples and exceptions, see this entry.
