An anapestic foot (known as an anapest) has two short syllables followed by a long syllable (SSL, or UU/).
Octameter is eight feet per line.
We couldn’t find any examples of poems written entirely in anapestic octameter – please let us know if you find one! If poems in this form do exist, they’re likely to go something like this:
We were ducking and diving and wheeling and whooping when old Mister
Misery told us to stop.
When we told him he wasn’t the person in charge he turned pink and then red and attacked with a mop.
