How it works
A noun can describe another noun: chicken soup, a bus stop, a toy store. Each sheet draws 8 of our 99 items, and the noun that describes almost always stays singular: a shoe shop, not a shoes shop.

Two sets
Set picks one. Make it short (49 items) turns a phrase into two nouns: a box for toys = a toy box, with toy, toys and toy's to choose from. Noun or adjective? (50) asks about the word in brackets: the bus stop against the big bus.
The very test
Put very in front of the word. A true adjective still works (a very big bus); a noun does not (a very bus stop).
Questions and answers
What is a noun used as an adjective?
A noun that sits in front of another noun and tells what kind: apple pie, winter coat, science fair. Grammar books also call it a noun adjunct or a noun modifier.
Why is it a shoe shop and not a shoes shop?
A noun that describes another noun usually stays singular, even when it means more than one: a toy box holds many toys. A few set phrases keep a plural, which is why our items avoid them.
Is there an answer key?
Yes. It prints as the last page unless you untick Add an answer key as the last page under More options. It circles the right answer under every item of the sheet you print.
