I love working out the origin of words: as a small child, around 4, I asked Mum where words came from but she didn't know. I ended up picturing a group of men in brown suits sitting round a table naming things. I suppose I thought men in suits ran everything.
Later at grammar school I did French, then Latin a year later, then German - all the languages taught me so much about word origins, and German made my local Yorkshire dialect seem so very legitimate.
The Indo-European language tree is a good way of picturing it all. We are on the Germanic branch of course. I often wondered what became of the Celtic language: we don't seem to have much of it in today's language. Then I found out our simple grammar with few inflections comes from there.
Here in Australia we have loads of new words; I use them all the time. Chooks for chickens is a good one: I have 7 chooks in my back yard i.e. back garden, and love to sit out there on a sunny arvo (afternoon)watching the greenies (lorikeets) fly over, and the cockies (cockatoos) too. We have words like rabbit-o and fish-o i.e. vendors.
I'm pretty sure some new words will crop up for Australian cricketers, but they'll probably not be fit for these pages.
