Seedbed → The word is formed from "seed" (from Old English "sǣd", meaning the reproductive part of a plant) and "bed" (from Old English "bedd", meaning a place to lie down or a plot of ground). A seedbed is a plot of ground prepared for planting seeds.
Think of a 'place' ('bed') where 'seeds' are planted — that's what a seedbed is.
