Which one to use?Beginnernounverb / noun

CellvsSell

'Cell' is a biological cell, a prison cell, or a phone cell; 'sell' means to exchange goods for money.

Side-by-side comparison

Cell
noun

"Cell" is a biological cell, a prison cell, or a battery cell. Also a unit in a clandestine organization.

  • Each cell in the human body contains the complete genetic blueprint of the organism.

  • He spent three years in a prison cell before the charges were dropped.

  • She forgot her cell at home and felt completely disconnected from work all day.

Sell
verb / noun

"Sell" is the verb to offer something in exchange for money. "They sell everything online". Its past tense is "sold".

  • The company plans to sell its flagship product in twenty new markets this year.

  • His job is to sell enterprise software to large corporations.

  • She managed to sell the idea to the board in less than ten minutes.

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

  • •"Cell" starts with C like "cage", "compartment", "contain", things enclosed.
  • •"Sell" starts with S like "store", "sale", "shop", commercial contexts.

Quick rule

  • •"Cell" = biological unit, prison room, or mobile phone.
  • •"Sell" = the commercial verb.

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.
