"delusive, deceptive, so as to impose upon by artifice or craft," c. 1400, present-participle adjective from beguile. Related: Beguilingly.
"mislead by false appearance or statement," c. 1300, from Old French decevoir "to deceive" (12c., Modern French décevoir), from Latin decipere "to ensnare, take in, beguile, cheat," from de "from" or pejorative (see de-) + combining form of capere "to take," from PIE root *kap- "to grasp." Related: Deceived; deceiver; deceiving.
mid-14c., "to be foolish, act the fool," from fool (n.1). The transitive meaning "make a fool of" is recorded from 1590s. Sense of "beguile, cheat" is from 1640s. Also as a verb 16c.-17c. was foolify. Related: Fooled; fooling. Fool around is 1875 in the sense of "pass time idly," 1970s in sense of "have sexual adventures."
early 15c., decepcioun, "act of misleading, a lie, a falsehood," from Old French déception (13c., decepcion) or directly from Late Latin deceptionem (nominative deceptio) "a deceiving," noun of state or action from past-participle stem of Latin decipere "to ensnare, take in, beguile, cheat," from de "from" or pejorative (see de-) + capere "to take," from PIE root *kap- "to grasp."
From mid-15c. as "state of being deceived; error, mistake;" from 1794 as "artifice, cheat, that which deceives."
"tending to mislead or give false impression," 1610s, from French deceptif (late 14c.), from Medieval Latin deceptivus, from decept-, past participle stem of Latin decipere "to ensnare, take in, beguile, cheat," from de "from" or pejorative (see de-) + capere "to take," from PIE root *kap- "to grasp."
In this sense in English it superseded deceptious (c. 1600), from French deceptieux, from Medieval Latin deceptiosus, from deceptionem; also deceptory (mid-15c.), from Latin deceptorious. Related: Deceptively; deceptiveness.
"to cause (time) to pass (without dullness)," 1630s, earlier "to occupy or engage (someone or something) for a period of time" (c. 1600), new formation from while (n.), not considered to be from Middle English hwulen "to have leisure," which is from a Germanic verb form of while (n.) (compare German weilen "to stay, linger"). An association with phrases such as Shakespearean beguile the day, Latin diem decipere, French tromper le temps "has led to the substitution of WILE v by some modern writers" [OED] (see wile (v.)).
late 14c., "to trick, beguile, jilt; to mock," also "to act foolishly; to speak jokingly, jest pleasantly," perhaps from Old French japer "to howl, bawl, scream" (Modern French japper), of echoic origin, or from Old French gaber "to mock, deride." Phonetics suits the former, but sense the latter explanation. Chaucer has it in the full range of senses. Around mid-15c. the Middle English word took on a slang sense of "have sex with" and subsequently vanished from polite usage. It was revived in the benign sense of "say or do something in jest" by Scott, etc., and has limped along since in stilted prose. Related: Japed; japing.
late 15c., "to divert the attention, beguile, delude," from Old French amuser "fool, tease, hoax, entrap; make fun of," literally "cause to muse" (as a distraction), from a "at, to" (from Latin ad, but here probably a causal prefix) + muser "ponder, stare fixedly" (see muse (v.)).
The original English senses are obsolete; the meaning "divert from serious business, tickle the fancy of" is recorded from 1630s, but through 18c. the primary meaning was "deceive, cheat" by first occupying the attention. "The word was not in reg. use bef. 1600, and was not used by Shakespere" [OED]. Bemuse retains more of the original meaning. Greek amousos meant "without Muses," hence "uneducated."
c. 1300, "trickery, treachery, lying," from Old French deceite, fem. past participle of deceveir, decevoir, from Latin decipere "to ensnare, take in, beguile, cheat," from de "from" or pejorative (see de-) + capere "to take," from PIE root *kap- "to grasp."
From mid-14c. as "act or practice of deceiving," also "false appearance, illusion." From late 14c. as "quality of being false or misleading."
Deceit is a shorter and more energetic word for deceitfulness, indicating the quality; it is also, but more rarely, used to express the act or manner of deceiving. The reverse is true of deception, which is properly the act or course by which one deceives, and not properly the quality; it may express the state of being deceived. Fraud is an act or series of acts of deceit by which one attempts to benefit himself at the expense of others. It is generally a breaking of the law; the others are not. [Century Dictionary]
