Greek pépōn denoted a variety of melon that was not eaten until it was fully ripe (the word was a noun use of the adjective pépōn ‘ripe’). Latin took it over as pépō, and passed it on to Old French as pepon. Through a series of vicissitudes this evolved via popon to early modern French pompon. This was borrowed into English in the 16th century, and soon altered to pompion; and in the 17th century the native diminutive suffix-kin was grafted on to it to produce pumpkin.

We have two (not so) super markets in my small town ,they both had pumpkins but not much to choose from — the other store had only huge ones. So I came home with two rather small ones. Tomorrow I start experimenting — I have some cookie recipes that I'll alter. Later I hope to have the strength to make a pumpkin dinner.
