Vainly a few diehard physicists pointed out that wings are of no propulsive help in airless void, that alate flight is possible only where there are wind currents to lift and carry.

There are no words branded into this gate, only the shape of a large bird with its wings stretched out over the width of the road like an alateprotector.
-- Jenny Siler, Easy Money
Alate is comprised of the Latin roots āla meaning "wing" and the suffix -ate which was used in Latin to make a word an adjective (like separate) but in English came to be used to create a verb out of a noun (like agitate).
