arvo
/ˈɑːvəʊ
/noun (plural arvos) Australian /NZ informal
Afternoon: on Monday arvo...
- A barbie in the arvo always sounds like a great plan and not in the slightest bit pretentious if suggested by an Australian.
- So after a rather wearing morning I only had the arvo to make the final arrangements.
- Milder conditions prevailed last Saturday with the greens recovering at a great rate and a north-easterly springing up in the arvo, making good scores a little tougher.
Origin
