Permission's own verb — what is allowed, held apart from what must; and the fifth month, spring in full.
Old English magan (to be able, to have power, to be strong enough), the modal verb narrowing over time from raw ability to permission specifically, while the month is a separate, unrelated borrowing from Latin Maius, named for the goddess Maia.
Permission's own verb — what is allowed, held apart from what must be. A door held open rather than a door forced.
