Question

Par for the course: how did this saying come to being in terms of golf?

Answer 1

A score on an even parallel for the course. PAR... just a guess.

Answer 2

The word par means equal. It is used in more than just golf. So this one is no big mystery. Par is a Latin word meaning equal. "On even par" means that two things are equal.

The term was used in golf to show what experts would typically score for each hole. People have just carried that word over into the English colloquial, "Par for the course", to mean that that is what is typically expected for the given situation.
