Remember 辙 through the idiom 重蹈覆辙 (chóngdǎo fùzhé) — to repeat the same mistakes, literally 'to tread again in the overturned ruts'. The cart radical (车) inside hints at wheel tracks.
usage
In Beijing colloquial speech, 辙 also means rhyme or rhyme scheme in opera and folk music. This is distinct from its literal meaning of wheel rut.
