jugular

the word 'jugular' originates from the latin term jugulum, which referred to the collarbone or the hollow part of the neck. this latin root is itself derived from the verb jungere, meaning 'to join' or 'to yoke', likely because the neck is seen as the part that joins the head to the body. the adjectival suffix -aris was added to form jugularis, meaning 'pertaining to the throat or neck'. this anatomical term entered english in the late 16th century, retaining its precise reference to the vital structures of the neck, most notably the large veins.

Structure: jugul (throat) + ar (adjective suffix) jugul (from latin jugulum, meaning 'collarbone, throat, neck'); ar (latin adjectival suffix -aris, meaning 'pertaining to').
