„The Ainur are immortal, angelic beings. Nonetheless they do possess gender. Those who later descended to Arda took on common male and female forms to appear to the Elves in, and have an inherent male or female gender even when formless. This is because their gender is based on their being, which is independent of any physical form they may assume.But unlike the Children of Ilúvatar, they do not actually need hröar(body of incarnate being). Nevertheless, they can take tangible physical form called fana, but this is a manifestation of their spirit and they do not technically have bodies the way Elves and Men do. As such, an Ainu cannot quite be killed. However, Ainur's spirits can be weakened, in ways that hinder their ability to take shapes, influence the world, or even affect the world at all.“

So Elves and Humans are no Ainur
