Oesophagus or Esophagus – Quick Answer
Both oesophagus and esophagus are correct.
- Oesophagus is used in British English
- Esophagus is used in American English
Examples:
- UK: Cancer of the oesophagus is a serious condition.
- US: The esophagus connects the throat to the stomach.
The meaning is exactly the same in both spellings.
The Origin of Oesophagus or Esophagus
The word comes from the Greek term “oisophagos,” meaning “gullet” or “food pipe.” It entered Latin and later English through medical and scientific writing.
British English kept the original “oe” spelling, which is common in older Greek-based medical words. American English later simplified many spellings to make them shorter and easier to write. As a result, “oe” became “e.”
This same pattern appears in other words, such as:
- Oestrogen → Estrogen
- Foetus → Fetus
That is why both spellings exist today.
