In the eighteenth century, grammarians began warning that singular they was an error because a plural pronoun can’t take a singular antecedent. They clearly forgot that singular you was a plural pronoun that had become singular as well. You functioned as a polite singular for centuries, but in the seventeenth century singular you replaced thou, thee, and thy, except for some dialect use.
