Is "stuffs" the plural of "stuff"?
Q:
My colleague recently told me that my desk was messy and I needed to clean my "stuffs" – is this really the plural of "stuff"?
A:
"Stuff" is an uncountable noun and the plural for it is also "stuff", not "stuffs". We understand that your colleague was trying to indicate all the different items on your desk with the usage of "stuffs", but "stuff" is an all-inclusive term that already refers to the collection of all the different items on your desk.

Now that you know that stuffs isn't the plural of stuff, find out if luggages is the plural of luggage.
