What does denticulated mean?
Denticulated is a formal adjective describing something edged or bordered with small, tooth-like projections — literally 'furnished with little teeth'. It appears most often in technical contexts: botanists use it for leaves whose margins carry minute, usually blunt teeth finer than those called serrate or dentate; zoologists apply it to shells, mandibles, and other anatomical structures bearing tiny tooth-like points; and architectural writers use it of mouldings ornamented with small tooth-shaped blocks. The word derives from Latin denticulatus, a diminutive built on dens, meaning tooth — the same root behind dental, dentist, and denticle. Its connotations are precise rather than figurative: it signals careful observation at a fine scale. A related noun, denticulation, names the condition or the individual projections themselves, and the shorter form denticulate serves as both adjective and verb.
adjectiveHaving a row or border of small tooth-like projections; minutely toothed. Used chiefly in technical description of leaves, shells, architectural mouldings, and similar structures.
- Bearing a row of small tooth-like projections along an edge or surface (used especially in botany, zoology, and architecture).
"The denticulated margins of the fern frond were visible only under the microscope."
"Under magnification, the beetle's denticulated mandibles revealed a fine comb of tiny points."
"The classical cornice featured a denticulated frieze echoing the dentils of Greek temples."
The same Latin root for 'tooth' that gives us 'dentist' also describes the microscopic saw-edge of a leaf — denticulated is what happens when teeth go miniature.

Etymology of denticulated
Denticulated comes from Latin denticulatus, formed from denticulus, a diminutive of dens ('tooth'), hence 'having little teeth'. English adopted the term around the early 17th century, largely through scholarly and scientific writing. It shares this root with a broad family: dental and dentist, indent and denticle, and the Italian-derived architectural term dentil. The verb denticulate ('to make tooth-like notches') and the noun denticulation belong to the same word family.

How denticulated is actually used
Formal and technical in register, appearing mainly in botany, conchology, zoology, and architectural description. In botanical terminology it implies teeth smaller and finer than those denoted by 'dentate' or 'serrate'. The shorter form 'denticulate' is equally common in scientific writing.
Easily confused with denticulated
Dentilated (or dentated in architecture) refers to square tooth-like blocks called dentils along a cornice, whereas denticulated describes any finely toothed edge or surface.
Serrated edges bear saw-like teeth that are typically larger and sharper than the minute, often blunt projections described as denticulated.
