No, that isn’t a misspelling

Recently I had an intense conversation with a five and a six-year-old. The conversation went as follows:

Child 1: I think it’s cozy.

Child 2: Or is it comfortable?

Adult with a whimsical sense of humor: “Maybe it can be both. Maybe it can be cozmfy — cozy and comfortable.” And because small children still have a vivid imagination and aren’t constrained by things such as the Merriam-Webster Dictionary, cozmfy made perfect sense to them.
