Humorous or Humourous: Which One Is Correct?

English is a language with many regional differences. One such difference can be found in the spellings of certain words between American and British English.

Many words ending with the suffix -or in American English are spelt with the longer -our suffix in British English. This distinction can be seen in many examples:

color (American) vs colour (British)

flavor (American) vs flavour (British)

honor (American) vs honour (British)

labor (American) vs labour (British)

humor (American) vs humour (British)

What about Humorous vs Humourous?

While humor is the accepted spelling in American English and humour in British English, it is important to emphasise that humourous is not the British spelling of the adjective humorous. It may be tempting to assume that the -our suffix in British English should be carried over to the adjective form as well, but this is not the case. The universally accepted spelling of the adjective form of humor/humour is humorous.
