said, spoken

Literally: said once

The story of the word

Short for ἅπαξ λεγόμενον, said once. Alexandrian scholars editing Homer flagged the words that appear a single time in the poems, because a word with no second appearance cannot be checked against itself and its meaning has to be inferred from context alone. The problem outlived them. Several Homeric hapaxes are still argued over, and the Hebrew Bible has a few hundred of its own.

The translator flagged the hapax and offered three readings in a footnote.

Roughly half the vocabulary of any large corpus turns out to be hapaxes.
