subs. (old cant).A scabbard. [The word is used nowhere in English save in Romeo and Juliet. It seems to be a literal due to an Elizabethan comp. Perhaps Shakespeare wrote pilch, Sir; perhaps he didnt. Anyhow pilch = a leathern coat, or overall, and was good enough business for a leathern sheath.]
1595. SHAKESPEARE, Romeo and Juliet, iii. 1. Will you pluck your sword out of his PILCHER by the ears?
