Prosody Glossary
When you start scanning Latin verse, you hit a wall of jargon — dactyl, spondee, caesura, elision, ictus, synizesis — and most of it is Greek shorthand for things Roman poets did automatically. This page is the lookup, not the lesson.
Use it as a reference while you read: the line Arma virumque canō, Trōiae quī prīmus ab ōrīs (Vergil, Aen. i. 1) is a hexameter of six feet, each a dactyl (— ⏑ ⏑) or a spondee (— —), with a caesura sitting somewhere in the middle of the third or fourth foot.
Every term in that sentence has a one-line entry below. Click through to the full Meter & Versification topics when you want the teaching.

— Verg. Aen. i. 1
Six feet, mostly dactyls and spondees — the canonical hexameter pattern. The pause after quī is the caesura; the line ends, as every hexameter must, with — ⏑ ⏑ — — (dactyl + spondee).
— Verg. Aen. iii. 658
Three elisions in one half-line — read aloud, you barely hear horrend(um), inform(e), just the next vowel taking over. Ecthlipsis is the same thing when the dropped final ends in -m.
Both name a word-break inside a line of verse, but they sit in different places relative to the foot.
word-end INSIDE a foot
arma virumque ‖ canō
pause cuts the third foot
word-end matches a foot boundary
...|...|...|‖|...|...
pause sits between feet
Tip: Ask: does the word end IN THE MIDDLE of a foot (caesura) or AT THE EDGE of a foot (diaeresis)?
In the line Arma virumque canō, Trōiae quī prīmus ab ōrīs, the phrase quī prīmus sits where one word ends inside the third foot. What is that pause called?
Study Tips
- •Start with the four foot shapes — dactyl (— ⏑ ⏑), spondee (— —), trochee (— ⏑), iamb (⏑ —). Almost every meter you'll meet in AP Latin is built from these.
- •When a line of Vergil sounds short by a syllable, look for elision — a final vowel (or vowel + m) gets eaten by the next word's opening vowel.
- •Don't memorize this whole list. Bookmark it and look terms up the first three or four times you see them — they stick fast once you've scanned a dozen lines.
