Correct spelling


Correct spelling, explanation: implement is the correct form; as a word of Latin origin, it is spelled similarly to the original word: implementem. There is no i after l. Impliment is thus an incorrect form; it may be caused by confusion with different words starting with impli-, like implicate. In this case, implement is the correct spelling.
