What does cuspidated mean?
Cuspidated is a technical adjective describing something that terminates in a sharp, abrupt point — a cusp. It appears most often in botany and zoology, where it characterizes leaves, petals, seeds, or teeth that narrow suddenly into a distinct tip, as in "cuspidated leaves" or "cuspidated molars." The word derives from the Latin cuspis, meaning a point or spear-tip, the same root that gives us "cusp" and "bicuspid." Because of its scientific register, cuspidated is rarely heard in casual conversation; writers reaching for a general-purpose synonym would more likely say "pointed" or "sharp-tipped." Its close cousin "cuspidate" is often used interchangeably, though "cuspidated," as a past-participial form, can suggest being furnished or armed with such points. For readers of field guides, anatomical texts, or species descriptions, recognizing cuspidated is a small but genuine aid to precision.
adjectiveHaving a point or points; ending in a sharp, cusp-like tip. Used chiefly in botany and zoology to describe leaves, teeth, or other structures that terminate in a distinct, abrupt point.
- (of a leaf, tooth, or similar structure) terminating in a sharp, abrupt point or cusp.
"The botanist noted the sharply cuspidated tips of the holly-like leaves."
"Under the microscope, each seed was revealed to be finely cuspidated at one end."
"The fossil shark's cuspidated teeth suggested a diet of hard-shelled prey."
From the Latin word for a spear's point, "cuspidated" is the technical term scientists use when a leaf or tooth ends in an unmistakable, needle-sharp tip.

Etymology of cuspidated
Cuspidated comes from the Latin cuspidatus, the past participle of cuspidare, "to make pointed," itself derived from cuspis, meaning a point or the sharp tip of a spear. The word entered English through scientific Latin, where naturalists adopted it to describe pointed structures in plants and animals. It shares its root with "cusp," "bicuspid," and "cuspidate," all preserving the sense of a sharp terminal point.
How cuspidated is actually used
A formal, technical term found mainly in scientific description — botany, zoology, and anatomy — rather than everyday speech. It is closely interchangeable with "cuspidate," to which it is related as a participial variant.
