ETYMOLOGY of ad-

latin

Component	Origin	Meaning
ad- / ac- / af- / ag- / al- / an- / ap- / as- / at-	Latin ad (ad)	“to,” “toward,” “near” — directional prefix (assimilates to the initial consonant of the following root: ac- before c, af- before f, ag- before g, al- before l, an- before n, ap- before p, as- before s, at- before t)

The word entered English in the 1400s as a Latin-derived prefix (prefix), borrowed from French a-, from Latin ad — literally “to, toward.” The prefix ad- (“toward”) connects ad- to the entire directional prefixes: adduct (ad- + ducere $\to$ to lead toward), adhesion (ad- + haerere $\to$ to stick to), and adrenal (ad- + renalis $\to$ toward the kidney). The directional prefix ad- is one of the most productive prefixes in medical terminology: e.g., adduction, adjuvant, afferent, append, and attrition.
