Note
Only the noun uses of eighteenth take a plural; the adjective, as in the eighteenth floor, never does. Most often the plural names fractions, following a numerator above one (five eighteenths, seventeen eighteenths), and terms sharing that denominator add directly. It can also count positions or, informally, birthday parties: two friends whose eighteenths fell in the same week.
