One example of a three-letter word that starts with "a" and ends with "o" is "ago."
Actually, it starts and ends with "M", but you remove the first "M" and insert an "O" ANYWHERE in the word, not just replace "M" with "O"
Some four letter words that start and end with O are:oleoOreoorzo
Five letter words that start and end with letter O are outdo and outgo.

No 5 letter word in the English language starts with the letter O and ends with the letter Z.

A seven (7) letter word that starts with M and ends with O: memento
One common exception is the word "mano" (hand), which is feminine even though it ends in -o.
