The "seed case" sense is recorded from the 1680s and is of uncertain origin, possibly a back-formation from the earlier podware ("seed of legumes"). The use of pod for a small group of whales or dolphins appeared in the early nineteenth century, also of unknown origin. The "detachable compartment" and single-use-container senses are twentieth-century extensions.
