Trolly or Trolley – Quick Answer
Trolley is the correct spelling.
Trolly is incorrect in standard English.
Correct:
- I pushed the shopping trolley in the supermarket.
- The airport trolley was full of luggage.
- The city uses electric trolleys for transport.
Incorrect:
- I pushed the shopping trolly.
- The airport trolly was broken.
If you want to write correctly in British, American, or global English, use trolley.
The Origin of Trolley or Trolly
The word trolley comes from the verb troll, which means “to roll” or “to move around.” In the 1800s, it was used for small wheeled carts. Later, it became popular for electric streetcars and shopping carts.
The ending -ey is common in English nouns:
- Donkey
- Monkey
- Valley
- Trolley
The spelling trolly likely appeared because people thought it should follow words like:
- Fully
- Really
- Slowly
But those words are formed differently. They are adverbs or adjectives. Trolley is a noun with a fixed spelling. English keeps many historical spellings, even if they seem inconsistent.
So the correct historical and modern spelling is trolley.
British English vs American English Spelling
Unlike words such as colour/color or organise/organize, there is no major spelling difference between British and American English for this word.
Both use:
Trolley
However, the meaning may differ slightly.
In the UK:
- A trolley is a shopping cart.
- It can also mean a wheeled serving cart.
In the US:
- A trolley often means a streetcar.
- Americans usually say shopping cart instead of trolley.
