Other forms: plentitudes
If you have more than enough of something, you've got a plentitude. If all your friends bring a dish to the potluck party, there will be a plentitude of food.
Plentitude is closely related to plenty, and they share the Latin root plenus, "full or complete." So whenever there's plentitude, there's plenty of something, whether it's a plentitude of sunny days in your summer or a plentitude of pillows on your comfy bed. Despite its kinship with plenty, this word is actually more commonly spelled without the first t, as plenitude.
