Repellant or Repellent – Quick Answer
The correct spelling is repellent.
Repellent means something that keeps away insects, animals, water, or unwanted things.
Examples:
- Use mosquito repellent before going outside.
- This jacket has a water repellent coating.
- The smell acts as a natural insect repellent.
Repellant is considered incorrect in modern English and should not be used in formal writing.
The Origin of Repellent
The word repellent comes from the Latin word repellere, which means to drive back or push away. Over time, the word entered English through French and kept its original meaning.
The ending -ent is common in English words that describe something performing an action, such as:
- Different
- Dependent
- Resistant
The confusion happens because many English words use the -ant ending, such as:
- Important
- Relevant
- Assistant
Since both endings sound similar, people sometimes write repellant by mistake. However, standard dictionaries and style guides recognize only repellent as correct.

Unlike many words, repellent has the same spelling in both British and American English. There is no regional variation.
