▶️ 起 (rise) + 到 (reach) = rise up to reach a role; 'play a part'
起 means rise/start; 到 means arrive/reach. Together 起到 literally 'rise-to', used for things that rise to fulfill a function or role — e.g. 起到作用 = play a role / have an effect.
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.'
到 — 刂 knife + 至 (phonetic, 'arrive')
到 is a semantic-phonetic compound. 至 ('to arrive') gives both meaning and sound, while 刂 (knife) was added later, likely as a phonetic reinforcer or to distinguish the written form. The core sense 'to arrive, reach' comes directly from 至, and 到 has carried that meaning since early script forms.
