Did you know?

Tutelage comes from the Latin verb tueri, meaning "to look at" or "to guard." When it first appeared in English at the turn of the 17th century, this word was used mainly in the protective sense of tueri; writers would describe serfs and peasants of earlier eras as being "under the tutelage of their lord." Over time, however, the word's meaning shifted away from guardianship and toward instruction. This pattern of meaning can also be seen in the related nouns tutor, which shifted from "a guardian" to "a private teacher," and tuition, which now typically refers to the cost of instruction but which originally referred to the protection, care, or custody by a parent or guardian over a child or ward.
