What does claviculate mean?
Claviculate is a rare technical adjective used in anatomy and zoology to describe an animal that possesses a clavicle, or collarbone, or something that relates to that bone. The clavicle is the slender bone linking the sternum to the shoulder, and its presence varies strikingly across the animal kingdom: humans, bats, and many primates are claviculate, while most hoofed mammals are not. In descriptive texts the word typically appears in formal scientific prose, characterising a specimen's skeletal features rather than everyday speech. Its obscurity is part of its character — even educated readers rarely meet it outside specialist literature. The word descends from the Latin clavicula, a diminutive meaning "little key", so named because the ancients thought the curved collarbone resembled a small key; that same root gives us clavicle, clavicular, and, through the idea of keys, instruments such as the clavichord.
adjectivePossessing or relating to a clavicle (collarbone); used chiefly in anatomical and zoological description of animals that have collarbones.
- Having a clavicle or collarbones (of an animal).
- Relating to or situated at the clavicle.
"Unlike many of its relatives, the bat is claviculate, its strong collarbones supporting the musculature of flight."
"The specimen was notably claviculate, a feature that helped place it among the more advanced primates."
"Radiologists examined the claviculate region for signs of fracture after the fall."
The word traces back to Latin "clavicula," literally "little key" — the Romans saw the collarbone's shape as a tiny key, which is also why musical "keys" live in words like clavier and clef.

Etymology of claviculate
Claviculate derives from the Latin clavicula, the diminutive of clavis ("key"), literally "little key", which the Romans applied to the collarbone because of its resemblance to a small key. English borrowed clavicula as "clavicle" in the early seventeenth century, and the adjective claviculate was formed later from the same stem, following the pattern of Latin-derived adjectives ending in -ate. Cognate forms include clavicular and, more distantly through the "key" sense of clavis, musical terms such as clavichord and clavier.
How claviculate is actually used
A rare, technical adjective confined almost entirely to anatomy, zoology, and paleontology; it will strike most readers as unfamiliar and should not be used in general writing where "having a clavicle" can simply be stated directly.
Easily confused with claviculate
"Clavicle" is the noun naming the collarbone itself, while "claviculate" is an adjective describing something that possesses or concerns a clavicle.
"Articulate" means fluent or clearly expressed (or jointed), whereas "claviculate" refers specifically to having a clavicle; the words share a similar rhythm and ending but nothing else.
