vocabulary

Before coming to Ireland, I was aware that people used different words for things, like biscuit for cookie and jumper for sweater. Here were a few that I hadn't heard before:

duster: chalkboard eraser
press: cupboard
minerals: soda/pop
half eight: half past eight (for the longest time I thought this meant four o'clock)

There are also a few Irish words in common use like Gardai for police. My Irish prof insists that people here say "geansai" for sweater/jumper, but I haven't heard anyone else use it.
