교(敎) – teach; instruct
The character 교 (敎) generally means “teach,” “instruct,” or “guide,” and appears in many Korean words related to education, moral guidance, and the transmission of knowledge. Words with 敎 often describe teaching environments, learning systems, religious instruction, and social values passed from one generation to the next.
