Bemused ≠ amused.
Bemuse means this:
1. To cause to be bewildered; confuse. See synonyms at daze.
2. To cause to be engrossed in thought.
See? It doesn't mean "To find things funny or droll." It rhymes with "confuse and it also means confuse? This should be so easy to remember. Maybe this will help: A Spanish translation of the verb is causar estupefacción . If you are bemused by something, it has stupefied you, not made you smile.
I've encountered several different people on the internet in the past week or so who have misused bemused, and it took every ounce of cool I have to stop my inner pedant from leaving them comments solely to correct their usage. Don't bemuse your readers or listeners by using bemused wrong, okay?> Thanks.
(Of course, 50 years from now, "to amuse" will surely find its way into the dictionary definitions of bemuse, just because so many people are using it that way. Sigh.)
