投げる
なげる · nageru · JLPT N4 · verb-ichidan
to pitch
⚾ 投 = hand (扌) + weapon (殳): the hand lets a spear fly
The kanji 投 joins the hand radical 扌 with 殳, an old sign for a striking weapon, so the core sense is sending something away by hand. Sound hook: nageru starts like nah, the word you say as you toss away something unwanted.
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.
