To be trite is to be worn out by constant use or repetition, or to be hackneyed or commonplace. The word “trite” is derived from the Latin word terere meaning essentially “to rub”. Thus, the word has physical associations, as if a trite remark actually erases its own origins because they are of no use anymore. Obviously the more used something is, the more trite it becomes, or so one would expect. There is even a built-in pejorative connotation, as to overuse a phrase, or resort to trite propositions can, in some cases, “rub” the listener the wrong way.
Since the very humble beginnings of the common law courts, judges have identified law that is trite. In the 15th century, Chief Justice Brian, in a case known only as T Pasch's case, said, in words that have since rung down the centuries:
Moreover…your having it in your own mind is nothing, for it is trite law that the thought of man is not triable, for even the devil does not know what the thought of man is.
