Three To's and an Oi is in Heather McHugh's 1999 poetry collection, The Father of the Predicaments. The title of the book comes from a line in Not a Prayer, one of the other poems in the collection: The father of the / predicaments, wrote Aristotle's translator, is being. In Three To's and an Oi, McHugh focuses on death and language, referring to the story of Cassandra, the woman to whom the god Apollo grants the power to see the future but then curses with the burden of never having her accurate predictions believed. The play Agamemnon, by the Greek dramatist Aeschylus (525-456 b.c.e. ), depicts Cassandra as knowing that she is about to be murdered and wailing otototoi. The title Three To's and an Oi refers to words that do not seem to be in the poem, but they appear in this focal word, otototoi. The presence of the to's and the oi is obscured because the oi is broken up, so that its o comes at the start of the poem and its i comes at the end. The poem questions why translators felt the need to render this cry woe is me, when it is clearly just the sort of emotional outburst, or baby talk, that people use when meaningful words are not adequate.
