Etymology: "Chelae" is simply the plural of "chela," the term for the pincer-like claw of a crab, lobster or scorpion. The singular traces back to the Greek word "khēlḗ," meaning "claw" or "crab's claw," which passed into Latin as "chele" and from there into scientific writing about animals. The surprising twist is that the same spelling also arrived in English from an unrelated source. In Hindi, "celā" means "disciple" or "pupil," and the English word "chela" borrowed that sense, so a single English form now covers both a crustacean's pincer and a follower of a teacher. The two meanings have entirely separate histories, converging only by coincidence of spelling.
