bemuse

First recorded in 1695–1705; be- + muse

The verb bemuse (usually as the adjective bemused ) is similar in sound to amuse , and has in fact taken on the meaning "to cause to be mildly amused." Many usage experts and traditionalists consider this a misuse of bemuse , pointing out that its proper meaning is “to bewilder or confuse.” However, the history and use of bemuse has shown that its meaning is often ambiguous. It's often the case that one's feelings are a combination of bewilderment and amusement: Their customs bemuse most Americans. Even when it clearly means "to bewilder or confuse," bemuse usually retains a lighthearted tone: one would not typically say: I was bemused by his motive for the murder.
