1540s, "to regard, notice with especial attention," from French respecter "look back; respect; delay" (16c.), from Latin respectere, frequentative of respicere "look back at, regard, consider," from re- "back" (see re-) + specere "look at" (from PIE root *spek- "to observe").
The meaning "treat with deferential esteem, regard with some degree of reverence" is from 1550s. The sense of "refrain from injuring or interfering with" is from 1620s. The meaning "have reference to, relate to" is from 1560s. Related: Respected; respecting.
To respect the person was "show undue bias toward (or against) based on regard for the outward circumstances of a person;" hence respecter of persons, usually with negative, from Acts x:34, in the 1611 translation.
late 14c., from Old French inspeccion "inspection, examination" (13c., Modern French inspection), from Latin inspectionem (nominative inspectio) "a looking into," noun of action from past participle stem of inspicere "look at, observe, view; look into, inspect, examine," from in- "into" (from PIE root *en "in") + specere "to look" (from PIE root *spek- "to observe"). Old English used onbesceawung as a loan-translation of Latin inspectio. Related: Inspectional.
"female monster with a petrifying look," late 14c., in Greek legend, any of the three hideous sisters, with writhing serpents for hair, whose look turned beholders to stone, from Greek Gorgones (plural; singular Gorgō) "the grim ones," from gorgos, of a look or gaze, "grim, fierce, terrible," later also "vigorous, lively," a word of unknown origin. Beekes' sources reject the proposed connections to Old Irish garg "raw, wild," Old Church Slavonic groza "shiver," Armenian karcr "hard."
Transferred sense of "terrifyingly ugly person" is from 1520s. Their names were Medusa, Euryale, and Stheino, but when only one is mentioned, Medusa usually is meant. Slain by Perseus, her head was fixed on the aegis of Athena.

"state or character of being perspicacious; keenness of sight, clearness of understanding," 1540s, from French perspicacité (15c.) and directly from Late Latin perspicacitas "sharp-sightedness, discernment," from Latin perspicax "sharp-sighted, having the power of seeing through," from perspicere "look through, look closely at," from per "through" (from PIE root *per- (1) "forward," hence "through") + specere "look at" (from PIE root *spek- "to observe"). An earlier word was perspicience "ability to see all things, infinite vision" (c. 1400).
