Deceive, mislead, delude, and beguile all mean "to lead astray" or "to frustrate," usually by underhandedness. Deceive implies imposing a false idea or belief that causes ignorance, bewilderment, or helplessness (as in "they tried to deceive me about the cost"). Mislead implies a leading astray that may or may not be intentional (as in "I was misled by the confusing sign"). Delude implies deceiving so thoroughly as to obscure the truth (as in "we were deluded into thinking we were safe"). Beguile stresses the use of charm and persuasion in deceiving (as in "they were beguiled by false promises"), and more generally describes the use of that charm to capture another's attention.

The Beguiling History of Beguile

A number of English words have traveled a rather curious path from meanings related to deception or trickery to something less unwelcome. A prime example is beguile, which first appeared in English around the 13th century in the sense “to lead or draw by deception.” For the next several centuries, most of the senses of the verb had to do, in one manner or another, with deceiving. Around the time of Shakespeare, however, the word took on a new sense, “to charm.” In a similar vein, fun was first recorded at the end of the 17th century as a verb meaning “to hoax or trick (someone).” It wasn’t until the middle of the 19th century that it began to be used as an adjective indicating that something was enjoyable. Amuse likewise started its life as a verb meaning “to divert the attention of (as from the truth or one's real intent).”
