A Chinese honorific suffix meaning 'master' or 'teacher', commonly seen in names like Lao Tzu or Sun Tzu.
From Classical Chinese 子 (zǐ), originally meaning 'child' or 'son', but evolved to denote respect for learned individuals. The term reflects Confucian values of honoring teachers and wisdom.
The transformation of 'tzu' from meaning 'child' to 'master' reflects a beautiful aspect of Chinese philosophy - the idea that true wisdom requires maintaining a childlike capacity for learning and wonder, making the student and teacher roles interconnected.
