Etymology: "Lithophagous" is a compound built from two Greek elements: "lithos," meaning stone, and "phagos," meaning eating. The first element survives in English in words like lithograph and monolith, while the second appears in phagocyte and anthropophagous. Put together, the pair describes an organism that feeds on or bores into rock, a sense that fits the way certain mollusks and sea urchins wear away limestone and other stone to make shelters. The suffix "-ous" is the English adjective ending, so the word works as a descriptive term for organisms rather than a noun for the creature itself. Its construction is transparent: a reader who knows the two Greek roots can decode it without a dictionary, which is typical of the scientific vocabulary built from classical parts that naturalists favoured.

Synonyms: stone-eating, rock-consuming, mineral-consuming, geophagous, substrate-eating
