類推

るいすい · ruisui · JLPT N1 · noun

analogy

類 (like, kind) + 推 (infer, push) = inferring from what is alike

類 means kind or resemblance, and 推 means to infer or push forward. 類推 is reasoning from a similar known case to an unknown one, which is exactly what an analogy does.

推 — hand radical 扌 + 隹 (short-tailed bird)
A semantic-phonetic compound: the hand radical 扌 gives the meaning 'to push' or act with the hand, while 隹 supplies the sound (originally close to 'tui'). The core sense has stayed remarkably stable, expanding from physical pushing to figurative uses like 'recommend' or 'infer'.
