Spoor
Definition: a trail left behind by something; an animal trail
This usually refers to an animal’s trail, but is also used to refer to a general trail of clues that something has happened. For example, we might leave a “digital spoor” as we spend time on the internet.
It comes from a Afrikaans word for “footprint.”
Why I Looked It Up
It was a NY Times crossword clue:
Wild animal’s trail
I actually got the word, but only by brute-forcing the individual letters.
