I'm unsure that this question would be on topic as it could prompt a list. If it isn't, can I rescue it?
Words that can be a Noun, Verb or Adjective.
I was posed a question the other day:
"Can you think of a word that can be used as a Noun, Verb or an Adjective?"
One such word would be "light". Are there others beyond some often quoted rude words?
Expanding on this,
Are there any words that could be taken to mean a Noun, Verb or Adjective depending on the interpretation of a single sentence?
Something that would satisfy 2 out of three is "This is a rubbish pile", i.e. is it a pile of rubbish, or a poorly-constructed pile.
