Uovo - egg
The word for egg in Italian is a bitch. One egg is uovo, masculine singular. Multiple eggs are uova, feminine plural. Yes, when a batch of eggs get together in Italy they change gender.
It's been the week of uova for me. As I was in Genova last weekend I didn't get to tuck into my eggs until Easter Monday. My mam had brought me over some goodies when she visited at the end of last month, and I'd managed to keep the two big eggs - one Dairy Milk, and one from Thornton's which was decorated with a design of a scooter in white chocolate! - to eat until it was actually Easter. And did I enjoy them!
