Common mistake
"I left my sell at home" when referring to the phone is wrong: the mobile phone is "cell". And "put him in a sell" for the prison room is also wrong: the room is "cell". "Sell" is only the commercial verb.
Trick to remember it
Quick rule
Did you know?
The word "cell" comes from Latin "cella" (small room). Medieval monks called their small monastery rooms "cells". When Robert Hooke looked at cork under his microscope in 1665, the tiny chambers reminded him of monks' cells. Paradoxically, Hooke was looking at dead cells, just their walls. Living cells were not observed until later. "Sell" comes from Old English "sellan" meaning to give or hand over, not originally about money at all.
