Meter

Definition-The measured arrangement of words in poetry, as by accentual rhythm, syllabic quantity, or the number of syllables in a line.


Example- 

• IAMBIC (x /) : That time of year thou mayst in me behold
• TROCHAIC (/ x): Tell me not in mournful numbers
• SPONDAIC (/ /): Break, break, break/ On thy cold gray stones, O Sea!

Significance- The importance of meter in poetry is to be more organized when your writing it and so it flows better.
