👉🧭 指 = finger (points) + 导 = lead; finger that leads = guide
指 means finger or to point; 导 means to lead or direct. Together 指导 is pointing-and-leading, i.e. to guide or give direction. Common in coach/mentor contexts like 指导老师 (supervising teacher).
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'.
