Etymology
the word is a modern anatomical term constructed from latin components. the prefix 'supra-' directly denotes a positional relationship of being above. the root 'clavicul-' originates from 'clavicula', meaning 'little key', as the romans thought the collarbone's shape resembled a small key. the suffix '-ar' is a standard adjectival ending. thus, the term's literal meaning, 'pertaining to above the little key', evolved through precise anatomical nomenclature to specifically denote the region superior to the collarbone.
