There's no furnitures or softwares!

I've mentioned this before in my blog and see it time and time again (esp. by Chinese people) and it's getting more and more irritating. There is no plural for words such as furniture or software. There is also no plural for sleepwear, footwear.. heck probably any word that ends in ware or wear. I think the only exception may be housewares.

These words are known as 'uncountable'. There are some more listed here.
