ento-
word-forming element used chiefly in biology and meaning "within, inside, inner," from Greek ento-, combining form of entos (adv., prep.) "within, inside," as a noun, "inner parts" (cognate with Latin intus), from PIE *entos-, extended form of root *en "in," with adverbial suffix *-tos, denoting origin.
entomb (v.)
"to place in a tomb, bury, inter," 1570s, from Old French entomber "place in a tomb," from en- "in" (see en- (1)) + tombe "tomb" (see tomb). Related: Entombed; entombing. The earlier verb was simply tomb (c. 1300).
entombment (n.)
"act of entombment; state of being entombed," 1660s, from entomb + -ment.
entomolite (n.)
"fossilized insect," 1813, from entomo-, from Greek entomon "insect" (see entomology) + -lite "stone." Late 18c. in French and German.
entomology (n.)
"the branch of zoology which treats of insects," 1764, from French entomologie (1764), coined from -logie "study of" (see -logy) + Greek entomon "insect," neuter of entomos "cut in pieces, cut up," in this case "having a notch or cut (at the waist)," from en "in" (see en- (2)) + temnein "to cut" (from PIE root *tem- "to cut").
Insects were so called by Aristotle in reference to the segmented division of their bodies. Compare insect, which is from a Latin loan-translation of the Greek word. Related: Entomological; entomologically. Hybrid insectology (1766, from French insectologie, 1744) is not much used.
entomologist (n.)
"one versed in or engaged in the study of insects," 1771; see entomology + -ist.
