There are certain words that, when used as a verb, mean the process of creating or transforming something into an instance of the word used as a noun. For example, to weave is to make strands of something into a weave. Likewise, writing is the action of creating writing, and if you spit, you end up with spit.
A few dubious examples: verb, sometimes humorously used as a verb meaning "to make a word into a verb." For programmers: if you diff something, the result is a diff. To edit can be said to produce an edit, as some people call edited versions of things.
Is there a name for this property? There must be many more (and better) examples; can you come up with any?
