What part of speech is the word scrap?

The word "scrap" can be several parts of speech depending on how it's used:

* Noun: A small piece or fragment of something, especially food. ("I had a scrap of paper with my notes on it.")

* Verb: To fight or argue. ("The kids were scrapping in the playground.")

* Verb: To gather or collect scraps of something. ("We scraped together enough money for a bus ticket.")

So, without context, it's impossible to determine the part of speech.
