📝📮 投 = throw/cast + 稿 = manuscript draft = cast your draft to a publisher
投 means to throw or cast (as in casting a vote, 投票), and 稿 is a manuscript or draft. Together: you cast your written draft toward an editor for publication. The toú sound also opens 投票 (to vote) and 投资 (to invest) — all forms of putting something forward.
投 — hand radical 扌 + weapon 殳
Originally a pictograph of a hand (扌) throwing or hurling a weapon or staff (殳). The core meaning 'to throw, cast, hurl' extended over time to figurative senses like 'to invest,' 'to deliver,' or 'to throw oneself into' something.
