Etymology: "Errorist" is a plain formation: the noun "error," meaning a mistake or deviation from what is correct, with the suffix "-ist," which forms nouns for people who practise, follow, or are characteristically engaged in something. Put together, the word names someone whose work or habit is making mistakes, a sense that the suffix makes sound like a profession or school of thought. The joke lies in the suffix. Because "-ist" so often marks a believer or practitioner (a socialist, a pianist, a fatalist), attaching it to "error" makes a mistake sound like a creed or a vocation. The word therefore reads as a humorous coinage rather than a term in standard use, and its effect depends entirely on that gap between the expected meaning of the suffix and the unexpected noun it is attached to.
