Definition: In poetry, meter is the basic rhythmic structure of a verse or lines in verse. It's a pattern of stressed and unstressed syllables.
Example:
"Trochee trips from long to short;
From long to long in solemn sort
Slow Spondee stalks; strong foot! yea ill able
Ever to come up with Dactyl trisyllable.
Iambics march from short to long;
With a leap and a bound the swift Anapaests throng;
One syllable long, with one short at each side,
Amphibrachys hastes with a stately stride;
First and last being long, middle short, Amphimacer
Strikes his thundering hoofs like a proud highbred Racer...
Significance: It makes the poem more interesting to read because we can have feelings when we read that poem. It will give the message to the reader when they feel excited and satisfy. In a poem must have meter in order to make the reader not fall asleep.
