Capsule

POD

Think of what holds seeds in a pea plant or carries astronauts into space—both share this short name.

"Capsule" hints at "pod" because both words describe small, enclosed containers—like a pea pod or a space capsule. The clue plays on the idea of something compact that holds contents, making "pod" a straightforward fit. It’s a direct definition without hidden wordplay, relying on the shared meaning of the two terms.
