the.com/grantee

means The person or party to whom something is formally granted — land, rights, a license, a deed.

from Built from 'grant' (from Old French 'granter/creanter', to promise or consent, ultimately tracing back to Latin 'credere', to believe or trust) plus the legal suffix '-ee', which marks the receiver of an action — the same pattern as employee or payee. The grantor does the granting; the grantee, by that tidy suffix, simply receives it.
