Did you know?

The verb defile (unrelated to this verb defile or its related noun) has a number of uses that are all variations on the idea of making something unclean or impure. These meanings echo the word’s Middle English and Anglo-French ancestry, where defilement is connected to figurative and literal trampling. The ultimate Anglo-French root is fuller, or foller, which means “to trample under foot,” “to oppress”—or literally, “to full.” Full in this case is a technical term: when you full woolen cloth you shrink and thicken it by moistening, heating, and pressing it. Originally, the pressing part was done by trampling it with the feet.
