Key Differences

Remember that "useful" is just "use" with a "ful" ending, not "full."
Count the letters: "useful" has only seven letters, while "usefull" unnecessarily adds an eighth.
Think of the term as a combination: use + ful.
The word "full" has two 'l's, but "useful" should not be full of 'l's—only one is needed.
"Useful" is useful with only one 'l' at the end.
