🪡🧵 Sounds like toss: toss it through and let it pass
通 means pass through, as in 交通 (traffic). 通す is the transitive form: you make something go through, like 針に糸を通す, threading a needle. Its intransitive partner is 通る, to pass by yourself.
通 — 辵 (辶) walk + 甬 yǒng (phonetic)
通 is a semantic-phonetic compound. The 辶 (chuò) component means 'walk' or 'movement', giving the meaning of going through or passing. 甬 (yǒng), originally depicting a hanging bell or a path, supplies the sound. Together they convey 'to pass through, communicate, connect'.
