naming convention opinion...

I'm front-end'ing a site for a client that has a 'favourite' or 'star-ing' functionality. 

My question is, how to name whether the item has been starred or not.

Current logic in my CSS has things that are already .is-open, .is-closed, .is-active, .is-inactive, .is-visible and .is-hidden

I'm currently toying with 

.is-favourited and .is-Notfavourited but that's pretty crap

Maybe .is-listed, .is-unlisted ?

Thoughts?

I would avoid using favourite in the class title just because the word has spelling variations.
