ETYMOLOGY of acr-

greek

Component	Origin	Meaning
acr- / acro-	Greek ἄκρον (akron), from ἄκρος (akros)	“extremities,” “highest point,” “tip” — anatomical combining form denoting distal body parts

The word entered English in the 1880s as acromegaly (noun), coined by Pierre Marie in 1886, borrowed from Modern Latin acro-, from Greek ἄκρον (akron) — literally “highest point” or “extremity.” The adjective acral appeared in the 1950s. The root akron (“highest point, extremity”) connects acr- to the entire extremity and position roots: acromegaly (acro- + megas $\to$ enlargement of the extremities), acrocyanosis (acro- + kyanos + -osis $\to$ bluish discoloration of the extremities), and acromion (acro- + ōmos $\to$ highest point of the shoulder). The combining form acr- is highly productive in rheumatology, dermatology, and endocrinology: e.g., acropathy, acrodermatitis, acromioplasty, and acromelalgia.
