“Uirthi” in Irish (on her / it): Meaning and Where It Comes From

Uirthi means on her / it. It is the preposition ar (on) and the pronoun sí (her / it) joined into one word. Irish does this with every simple preposition; the joined words are called prepositional pronouns, forainmneacha réamhfhoclacha.
