in poetry, denotes half a verse, or a verse not completed.

Of this there are frequent examples in Virgil's Æneid; but whether they were left unfinished by design or not, is disputed among the learned: such are, Ferro acinicia vocat, Æn. II. v. 614. And, Italiam non sponte sequor, Æn. IV. v. 361.

In reading common English verses, a short pause is required at the end of each hemistich or half-verse.
