In Latin and Greek poetry, correption (Latin: correptiō [kɔrˈrɛpt̪ioː], "a shortening")[1] is the shortening of a long vowel at the end of one word before a vowel at the beginning of the next.
Thus, the scansion of the second line is thus: πλαγχ θε, ε | πει Τροι | η ςι ε | ρον πτο λι | εθ ρο νε | περ σε 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.
[3] This is called Attic correption, sometime known by its Latin name correptio Attica.
Therefore, the first syllable of a word like δᾰ́κρυ could be scanned as "δά | κρυ" (open/short), exhibiting Attic correption, or as "δάκ | ρυ" (closed/long), in keeping with the conventions of Homeric verse.
