'seedpod' originates from the combination of 'seed' and 'pod', where 'seed' refers to the reproductive unit of a plant and 'pod' refers to a casing or shell.

'seedpod' evolved from the Old English word 'sǣd' for 'seed' and the Middle English 'pod' for 'casing'.

Initially, it referred to any casing containing seeds, and this meaning has largely remained the same in modern usage.
