Etymology: Ancient Greek "leichēn" named tree moss and similar crusty growths, and it is probably linked to "leichein", meaning "to lick". The name may reflect how these organisms seem to cling to rock and bark as if licked onto them. The modern term is built from three parts. "Lichen" supplies the subject, "-logy", from Greek "logos" (word, reason, study), names the field, and "-ist" marks a practitioner. A lichenologist, then, is someone who studies lichens, formed on the same pattern as "biologist" and "geologist".
