circum-

circum-

a prefix with the meaning “round about, around,” found in Latin loanwords, especially derivatives of verbs that had the general senses “to encompass or surround” (circumference; circumjacent; circumstance ) or “to go around” by the means or in the manner specified by the verb (circumnavigate; circumscribe ); on this basis forming adjectives in English with the meaning “surrounding” that named by the stem (circumocular; circumpolar ).

Origin:
< Latin circum around (accusative of circus; see circus, circle), orig. as an adv. fixed in relation to the v., later construed as a prefix
