Etymology: "Denticulus" is a Latin diminutive of "dens," meaning "tooth," so its literal sense is "little tooth." The suffix "-culus" (feminine "-cula," neuter "-culum") was used throughout Latin to make small versions of nouns, as in "particula" (little part) or "vesicula" (little bladder). The word is a direct borrowing into English from Latin, used mainly in botany, zoology and anatomy to name tiny, tooth-shaped projections, such as the minute serrations on a leaf margin or the small toothlike ridges on a shell or bone. Because it is a technical coinage built from a classical root, it was not a word that ancient Romans used for anatomical or scientific features. Like many scientific terms, it was formed from existing Latin materials when naturalists needed a precise name for structures that common vocabulary did not describe.

Synonyms: small tooth, toothlet
