Brain Game: What a Relief

Good luck with this week's Wednesday Wordplay challenge.

What common, four-letter, one-syllable English word can be converted into a three-syllable English word by adding an "O" to its end?

Here is my ANSWER.

MY ANSWER:

CAME. By adding an "O" to its end, it becomes the three-syllable word  CAMEO.

IMPORTANT NEW NOTE: Clever readers discovered additional answers RODE (RODEO). and MIME (MIMEO). Nice job!
