What does it mean entitled in reversion expectant on the tenancy?

"Entitled in reversion expectant on the tenancy" refers to a legal interest in property where a party holds a future right to ownership or possession once the current tenancy expires. This means that while someone else is currently occupying the property under a lease or tenancy agreement, the reversioner has a claim to the property that will take effect after the tenant's rights end. Essentially, it's a way of describing a future interest in property that will revert to the owner once the current tenant leaves.
