講

It is a phono-semantic compound, composed of:

言 (“speech, words”) as the semantic element;

冓 (gu, structure/assemble) as the phonetic element.

The combination expresses the idea of structured or organized speech — explaining, teaching, or settling matters through words.

In Korean usage, 강 (講) is common in educational, explanatory, and rhetorical contexts:

강의 (講義) – lecture

강연 (講演) – speech, public lecture

강론 (講論) – sermon, discourse

강독 (講讀) – reading aloud with explanation

강습 (講習) – study, training class

강좌 (講座) – lecture course, class

강단 (講壇) – lecture platform, pulpit

Thus, 講 primarily carries the sense of formal teaching, explanation, or speech, and by extension instruction and reconciliation through words.
