monotheist

The word 'monotheist' is a modern English formation built from classical Greek components to describe a specific theological concept. The first element, 'mono-', originates from the Proto-Indo-European root men- meaning "small, isolated," which evolved into the Greek term for "single" or "alone." This combines with '-the-', derived from the Greek word for a god, which may trace back to the PIE root dhes-, used for forming religious concepts. The agent suffix '-ist' completes the term, creating a noun for an adherent. Thus, the word's construction follows a clear, logical path from its literal Greek parts—"one" + "god" + "believer"—to its modern abstract meaning denoting a person committed to the belief in a singular deity, contrasting with polytheism.

Structure: mono (one) + the (god) + ist (person who believes in) - mono: From Greek μόνος (monos), meaning "alone, only, single." Acts as a combining form meaning "one" or "single." - the: From Greek θεός (theos), meaning "god." Acts as a root element denoting deity or divinity. - ist: From Greek -ιστής (-istēs), via Latin -ista, denoting an agent noun suffix meaning "a person who practices or believes in" something.
