Etymology: from Latin tūtēla, watching, keeping, guardianship (from tūt-, participle stem of tuērī, to watch).
"So, having made his arrangements and offered vows to the gods, when he was seen in the streets advancing at the head of his men to engage the enemy, a confused noise of shouts, congratulations, vows, and prayers was raised by the Syracusans, who now called Dion their deliverer and tutelar deity, and his soldiers their friends, brethren, and fellow-citizens" (Plutarch's Lives Translated From the Greek by Several Hands, John Dryden (trans.), 1683).
