🧭 指南 = point (指) + south (南); the old south-pointing compass that guides you
指 means point and 南 means south. Ancient Chinese compasses pointed south, so to point-south came to mean to guide or a guidebook.
指 — hand radical 扌 + 旨 (zhǐ, phonetic)
指 is a semantic-phonetic compound. The hand radical 扌 gives the meaning — something done with the hand, namely pointing with a finger. 旨 supplies the sound 'zhǐ'. From 'finger' it naturally extended to the verb 'to point' and figurative senses like 'to indicate' or 'to refer to'.
南 — 十 ten + 冂 enclosure + 丷 + 干
Originally a pictograph of a bronze bell or musical instrument hung on a frame, used in southern regional rites. Through phonetic loan, the character came to mean 'south' — the direction one faces when seated as ruler in ancient China. The original 'bell' meaning was lost.
