From today's word of the day email an opsimath is a late learner. Here is one of the examples...
1883 Church Times 9 Feb. 97 Those who gave the name were not simple enough to think that even an opsimath was not something better than a contented dunce.
Is he saying an opsimath is better or no better than a contented dunce?
I am presuming what the phrase means but can not be certain.
