起劲

enthusiastically
💪 起 (rise) + 劲 (strength/energy) = doing something with rising energy, vigorously
起 means to rise or start up; 劲 means strength or vigor. Together they describe acting with energy that is ramping up, hence vigorously or enthusiastically. Sound: chee-jin.
起 — 走 (run) + 己 (self/phonetic)
起 combines 走 'run/walk' as the meaning component with 己 as the phonetic component. The 走 element suggests movement of the body, giving the core sense of rising up or starting to move. From there it extended to meanings like 'get up,' 'begin,' and 'arise.'
