"Swarfed" is not a recognized word in the English language. It's possible you've encountered a misspelling or a term specific to a certain field.

To help me understand what you're looking for, could you provide more context?

For example:

* Where did you see this term? (a book, website, conversation)

* What was the topic being discussed?

* What other words were used in the context?

With more information, I can try to decipher the intended meaning.
