Due diligence: I have Googled the word "surgery," and I have reviewed a couple of dozen past questions on this site related to the word "surgery." I have not found a satisfactory answer to the question which follows.
I hail from the United States. I recently had occasion to consult the website of the British Parliament. I noticed that in the sections for individual members the word "surgery" would often occur along with a listing of days and times. Internal evidence suggested that I should interpret "surgery" to mean "office hours" -- i.e., when a person could expect to find the M.P. in the office.
First of all, is my conception correct?
If so, how did "surgery" come to have this non-medical connotation?
Thanks to all who have offered, or will offer, answers.
