经 /jīng/ A CANON / ALREADY, EXPERIENCE, DIRECTOR and much more…
Primary meaning is A CANON (that is the official text or a sum of official texts of a particular culture).
When something has ALREADY happened, we can find a mention of it in A CANON. So it shouldn’t surprise us that we find the character 经 /jīng/ in the word 已经 /yǐjīng/ ALREADY.
When we have ALREADY been through something, we have THE EXPERIENCE 经验 /jīngyàn/.
DIRECTOR 经理 /jīnglǐ/ is someone who sets (or “canonises”) the ORDER 理 /lǐ/ of a company.
