rectum: rectum: [16] Rectum is one of a range of words bequeathed to English by Latin rēctus ‘straight, correct’ (a distant relative of English right). Others include rectangle [16], rectify [14], and rectitude [15]. Rectum itself is short for rēctum intestīnum ‘straight intestine’ – a term contrasting the rectum with the convolutions of the remainder of the intestines.
=> direct, rectify, rectitude, right
rectum (n.): early 15c., from Latin intestinum rectum "straight intestine," in contrast to the convolution of the rest of the bowels, from neuter past participle of regere "to straighten" (see regal). A loan-translation of Greek apeuthysmeon enteron, "the name given to the lowest part of the large intestine by Galen, who so called it because he dissected only animals whose rectum (in contradistinction to that of man) is really straight" [Klein].
