Etymology: "Mossologist" is a modern coinage built from "moss" and the suffix "-ologist," which denotes a specialist who studies a particular subject. The suffix comes from "-ology," itself formed from Greek "logos" ("word, study") plus "-ologist" from the Greek agent ending, so the term follows a pattern used for countless scientific fields, from geologist to mycologist. Moss, in turn, comes from Old English "mos," meaning bog or marsh, a sense that survives in place names and in the older word "moss" for peat bog. The plants were named for the boggy ground where they grew, so the botanical study of mosses inherited a name that originally described a wet landscape rather than the small green plants themselves. Because "mossologist" is a playful or specialist formation rather than a long-established term, it appears mainly in informal and popular writing. Its meaning is transparent from its parts, which is why it can be understood without a dictionary entry, even though the field it names is formally called bryology.
