ETYMOLOGY of a-

greek

Component	Origin	Meaning
a- / an-	Greek ἀ- (a-), ἀν- (an-)	“not,” “without,” “lacking” — negating/privative prefix (becomes an- before h or a vowel)

The word entered English in the 1600s as a Greek-derived prefix (prefix), borrowed from Late Latin a-, from Greek ἀ- (a-) — literally “not, without.” The root a- (“absence”) connects a- to the entire negative and privative roots: anemia (an- + haima $\to$ without blood), anoxia (an- + oxys $\to$ without oxygen), and asymptomatic (a- + symptoma $\to$ without symptoms). The privative prefix a- is one of the most productive negating prefixes in medical terminology: e.g., anhydrosis, aneurysm, aphonia, asystole, and achylia.
