Learn how to say Humorously correctly in English with this tutorial pronunciation video.
Oxford dictionary definition of the word humorous:
causing laughter and amusement; comic:
a humorous and entertaining talk
having or showing a sense of humour:
his humorous grey eyes
Note that although humor is the American spelling of humour, humorous is not an American form. This word is spelled the same way in both British and American English, and the spelling humourous is regarded as an error.
If a word ends in -our (in this case humour), change -our to -or before adding -ous, -ist, and some other endings: humorous; humorist.
