Do you speak English? Vol.2

Another word I picked up from the conversation with a British client lately:

• arvo /ˈɑːvəʊ/noun, austral informal afternoon

And while looking for the previous one I had to look the next one as well:

• austral /ˈɔːstrəl/adj: of or coming from the south: austral winds

Etymology: 14th Century: from Latin austrālis, from auster the south wind
