Fing = ? Groce = ?

It's about the oddly idiosyncrasies and inconsistencies of the English language.

Write is the verb to the noun writer. The person is asking why fing and groce aren't accepted verbs that can be associated with the nouns fingers (digits on the hand) and grocers (a person who works in a grocery store).

Fing and groce don't exist in the English language as words.

Ham does exist as a word in forms of a noun, (the meat from a pig), and a verb defining an action related to joking or silly acting. Though it isn't related verb wise to the tool of a hammer.

Thanks
