simplist

Simplist is a seldom-used English noun and, less commonly, an adjective formed from simple with the agent noun suffix -ist. It generally designates a person who advocates or adheres to simplism—the idea that complex matters should be explained or approached through simple, straightforward means. Because the term is not widely recorded in major dictionaries, its precise meaning can vary by author and context; in many cases it is a coinage or a neologism rather than a standard entry.

Etymology: The word derives from the adjective simple, itself from Latin simplex, with the agent suffix -ist used to form a noun indicating a believer or practitioner.

Usage: In prose, simplist may describe someone who argues that complex issues should be treated with straightforward explanations or solutions. Depending on context, it can carry neutral, approving, or pejorative connotations, especially when contrasted with nuance, rigor, or complexity. In everyday writing, speakers often substitute “advocate of simplicity” or “proponent of simplicity” to avoid ambiguity.
