The Origin of Slew vs Slough
Understanding history makes the difference clearer.
Origin of Slew
The word slew comes from Old Norse slœgja, meaning “to turn.” Over time, English speakers began using it to describe sudden sideways movement. Later, in American English, it developed an informal meaning: a large quantity. That is why phrases like slew of people or slew meaning many became common in newspapers and conversation.
Origin of Slough
Slough has Old English roots from slōh, referring to mud or marshland. The word later gained another meaning: shedding dead skin or tissue. In medical and biological contexts, it still means removal or peeling away.
The spelling differences exist because English borrowed words from different languages at different times. Even though the words look alike today, they evolved separately.
