Definition and Meaning of Fuelled or Fueled

Fuelled and fueled are the pasttense and pastparticiple forms of the verb fuel. Both spellings have the same meaning.

The word fuel can refer to a substance that produces energy, such as petrol, diesel, gas, or coal. It can also describe something that increases an emotion, activity, or situation.

Fuelled or Fueled as a Physical Energy Source

Use the word when something supplies energy to a machine, vehicle, or system.

Examples:

• The company fuelled the aircraft before takeoff.
• The storm fueled the fire by spreading hot embers.
• The power station was fuelled by natural gas.
• The truck was fueled before its long journey.

The word can also describe something that encourages action or strengthens a feeling.

Why Are Fuelled and Fueled Spelled Differently?

The difference comes from regional spelling conventions.

In British English, writers often double the final l when they add certain endings to words that end in a vowel followed by l. This pattern gives us fuelled.

American English usually keeps one l in this form, producing fueled.

The same pattern appears in other words:

• Travelled / Traveled
• Cancelled / Canceled
• Labelled / Labeled
• Modelling / Modeling

These pairs show a common spelling difference between British and American English.

However, spelling patterns can vary from word to word. It is best to check a reliable dictionary if you are unsure about a particular form.
