In this paper, I show data about switching of Hearer-honorification endings in Korean and argue there is a licensing principle for those switching phenomena. The licensing principle is as follows. Licensing Principle for Switching of Hearer-honorification endings in Korean(LPSH) : In a cluster of speech in which a speaker talks to a hearer once, one to one concord must be possible between honorific levels of final endings included in it. (N.B. Concord pairs are only as follow: 1-2, 2-3, 3-4; A-1, A-2; A-B; B-1, B-2, B-3, B-4) In the note of LPSH, both the numbers(i.e. 1, 2, etc) and the signs A, B represent Hearer-honorification levels in Korean: the numbers mean formal honorific levels(i.e. 1>2>3>4). And the signs represent informal honorific levels(i.e. A>B). LPSH is very interesting itself. It also shows us that it is at least partly possible in Pragmatics to define a principle formally like in Syntax.
