“Fúibh” in Irish (under you (plural), about you (plural)): Meaning and Where It Comes From

Fúibh means under you (plural), about you (plural). It is the preposition faoi (under) and the pronoun sibh (you (plural)) joined into one word. Irish does this with every simple preposition; the joined words are called prepositional pronouns, forainmneacha réamhfhoclacha.
