Morphology

acromioclavicular = acromion + clavicle (transparent) = acromio + clavicul + ar

The adjective is formed from the combining forms referring to the acromion and the clavicle plus the common adjectival suffix '-ar'; if the anatomical base terms are known the meaning is directly predictable.

Etymology

Acromioclavicular comes from the parts acromion meaning 'top' of the shoulder and clavicle meaning 'collarbone'. Acro- means 'top', as in acrobat, so the word names the joint where the collarbone meets the top of the shoulder.
