Cell and sell are pronounced the same, so your ears cannot tell them apart. The only clue is the job each word does: sell is an action, and cell is a thing.
- Sell is a verb: a doing word. It means to give something for money, or to persuade someone.
- Cell is a noun: a naming word. It is a tiny unit, a part of a battery, a box in a spreadsheet, or a short way to say cell phone.
Sell: the doing word
Sell means to give something to someone in exchange for money. It can also mean to persuade someone to accept an idea. It always works as an action, so it sits near words like to, will and can.
We sell lemonade at the school fair.
He will sell his old bike.
The shop sells fresh bread.
Can you sell me one ticket?
Our class had to sell the idea of a garden to the head teacher.
Cell: the tiny unit
Cell is a noun, and it names a small part of a bigger whole. Its everyday senses include the living unit of plants and animals, the power box inside a battery, the box in a spreadsheet, and cell phone.
A plant cell is very small.
Each cell in a spreadsheet holds one number.
A battery cell gives the toy car its power.
Her cell phone is on the desk.
Easy way to tell them apart
Look at the words around the gap. Is someone doing something for money, or trying to persuade someone?
- After to, will, can or a person's name doing the action: sell.
- After a, the or each, or in front of phone: cell.
💡 The OddLingo Trick
Sell and sale belong together. When you sell something, you make a sale. If sale fits in the gap, the verb you want is sell.
⚠️ Common mistakes

📌 Good to know
Just starting out? You can safely skip this part.
Because the two words sound the same, a sentence can look right in writing and still be wrong. When a word feels odd, check whether it is doing an action or naming a thing. If you are thinking about another pair that is about giving and taking, see Lend vs Borrow.
