detritus
noun

Did you know?
If you use detritus in speech, remember to stress the second syllable, as you do in the words arthritis and bronchitis. Once you've mastered its meaning and pronunciation, you’ll find that detritus is a term—originally a geology term referring to loose material, such as broken rock fragments, resulting from disintegration—that can be applied in many situations. After the first hard freeze of fall, gardens are littered with the detritus of summer’s plants and produce: stalks, leaves, vines, and maybe even an abandoned hand trowel. As a flood-swollen river retreats to its banks, it leaves detritus—debris gathered by the raging waters—in its wake. The detritus of civilization may include junkyards and abandoned buildings, while mental detritus may include all kinds of useless trivia. (We’re not saying it qualifies as such, but detritus comes from the Latin root deterere, meaning “to wear away, impair.”)
