Seediest → It is formed from "seed" (from Old English *sǣd*, meaning the reproductive part of a plant) and the suffix "-iest" (meaning most). The word "seediest" refers to something that is most full of seeds or, in a figurative sense, something that is the most disreputable or shabby.
Think of 'seed' as the part of a plant that can grow into something new, and when something is described as 'seediest', it means it is the most shabby or disreputable, like a neglected garden.
