Correct spelling, explanation: adjective-creating suffix -ful gives the meaning of full of, characterized by, and is always spelled with one l. This may not be obvious since it’s a different spelling from the word full. Thus useful will also be written with just one consonant l.
Usefull is the wrong form.
