Why is this?
Some grammar rules are easy to explain to my 5-year-old.
Some are not.
This one is not:
Mouse x 2 = mice
Louse x 2 = lice
Blouse x 2 = blouses
House x 2 = houses
Spouse x 2 = spouses
ice/ice = ice
rice/rice = rice
Why? Is it because typically there is never a single ice/ouse?
Or that most commonly people aren't afflicted with a multitude of hice or spice, but have just one?
Is the "ice" plural used only for the animate? Because my spouse = totally animate.
If you double-douse someone, you usually haven't diced them. At least not simultaneously.
