💬 提 = lift/raise (a topic); 到 = arrive at — raise it until it reaches the conversation
提 means to lift or carry by hand (扌 hand radical + 是); 到 means to arrive. Together: to lift a subject up so it arrives in the discussion — i.e. to mention or bring up.
提 — hand radical 扌 + 是 (phonetic)
提 is a semantic-phonetic compound. The hand radical 扌 gives the meaning, since the character originally referred to lifting or carrying something by hand. The right side 是 supplies the sound. From 'lift up' it extended to 'raise (an issue),' 'mention,' and 'bring forward.'
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.
