What does dentated mean?
Dentated is a formal adjective describing something edged or surfaced with tooth-like projections — a row of small, pointed notches rather than a smooth line. It appears most often in scientific description: a botanist may note that a species has dentated leaves, meaning its margins bear sharp, outward-pointing teeth, while a zoologist might describe dentated claws, shells, or jaw structures. The word derives from the Latin dens, dentis, meaning "tooth," the same root behind dentist, dental, and trident. Though it can describe anything from architectural battlements to geological formations, dentated is rarely heard outside technical or literary contexts; everyday English prefers "toothed" or "jagged." Its closest synonym is "serrated," though serration typically implies slanted, saw-like teeth while dentation suggests more upright ones. Writers reaching for precision in natural history or descriptive prose will find it a useful, exact term.
Having teeth or tooth-like projections along an edge or surface.
"The beetle's forelegs were strongly dentated, an adaptation for gripping bark."
(Botany) Of a leaf margin, edged with outward-pointing, saw-like teeth.
"Field guides distinguish the dentated leaves of this elm from the smooth-margined beech."
In current botanical usage, the shorter form "dentate" is preferred.
Every time you say "dentist," you're speaking Latin for "tooth" — and "dentated" simply means nature gave something a mouthful of them.

Etymology of dentated
Dentated comes from the Latin dens (stem dent-), meaning "tooth," combined with the participial ending -atus to form Late Latin dentatus, "toothed." English adopted it via forms such as dentate, with "dentated" arising as an extended adjectival variant, likely by analogy with words like "pointed" and "notched." The same root produced dental, dentist, denture, trident, and indent. The word has been used in English scientific description since at least the early modern period, particularly as botanical terminology became systematized in later centuries.

Formal and largely technical in register, appearing chiefly in botany, zoology, paleontology, and descriptive anatomy. In modern botanical writing the simpler form "dentate" has largely displaced it. Not used of literal teeth themselves.
