In Latin and Greek poetry, correption ( , "a shortening") is the shortening of a long vowel at the end of one word before a vowel at the beginning of the next. Vowels next to each other in neighboring words are in hiatus.
Homer uses correption in dactylic hexameter:
Here the sequence ÷ õ in bold must be pronounced as õ õ to preserve the longâÂÂshortâÂÂshort syllable weight sequence of a dactyl. Thus, the scansion of the second line is thus:
Typically, in Homeric meter, a syllable is scanned long or "closed" when a vowel is followed by two or more consonants. However, in Attic Greek, a short vowel followed by a plosive and a liquid consonant or nasal stop remains a short or "open" syllable. This is called Attic correption, sometime known by its Latin name correptio Attica.
Therefore, the first syllable of a word like ôᾰ́úÃÂàcould be scanned as "ôì úÃÂà" (open/short), exhibiting Attic correption, or as "ôìú ÃÂà" (closed/long), in keeping with the conventions of Homeric verse.
