Deskill is formed from "de-" (meaning down or away) and "skill" (from Old Norse *skil*, meaning knowledge or ability). The word describes the process of reducing or removing skill or ability from a task or job.
Think of 'removing' ('de-') someone's 'ability' ('skill') — that's why deskill means to take away skill.
