Peppa

Not long ago, Peppa may have been at risk for confusion with the name Pepper. But thanks to the British children's TV series Peppa Pig, Peppa is now a household name. If your household contains preschoolers, that is.

The name is so tied up with its porcine spokesperson that it's been rendered almost unusable for a child. Try Pippa instead, or use Peppa on a pet.

Pronounced PEP-uh.
