What distinguishes a lease under Section 105 of the Transfer of Property Act, 1882 from a bare licence under Section 52 of the Indian Easements Act, 1882?

Under section 105 of the Transfer of Property Act, 1882 a lease is a transfer of a right to enjoy immovable property, so the lessee takes an interest in it. Under section 52 of the Indian Easements Act, 1882 a licence is only a right to do something on the land that would otherwise be unlawful, and it “does not amount to an easement or an interest in the property”. A licence transfers neither ownership nor an interest, and under section 60 it is generally revocable unless it is coupled with a transfer of property or the licensee has executed permanent work on it, so it is not always irrevocable.
