The Lake Poets were a group of English poets: Samuel Taylor Coleridge, Robert Southey, and William Wordsworth. They lived in the "Lake District" in northwestern England. This group was part of the Romantic Movement of the late 1700's and early 1800's.

Named for a 12th century poet, Leonius, who first composed such verse, it consists of hexameters or of hexameters and pentameters in which the final syllable rhymes with one preceding the caesura, in the middle of the line.

Light verse consisting of five lines and rhymed: a-a-b-b-a. The first, second and fifth lines contain three feet while the third and fourth lines contain two feet.
A light or humorous verse form of five chiefly anapestic verses of which lines one, two and five are of three feet and lines three and four are of two feet, with a rhyme scheme of aabba. The limerick, named for a town in Ireland of that name, was popularized by Edward Lear in his Book of Nonsense published in 1846 — the form was popularised by Victorian poet Edward Lear.

Ogden Nash is renowned for humorous short poetry, and often used the limerick form:
"There once was a miser named Clarence
Who Simonized both of his parents;
"The initial expense,"
he remarked, "is immense,
But it saves on the wearance and tearance."

Litotes is a figure of speech. This form is generally used in a humorous context. It creates an impact by denying the opposite of what is true and an understatement is employed for the purpose of enhancing the effect of the ideas expressed:
"I never said I didn’t hit him
The burglar didn’t mind the diamonds he found"

The term is used to refer to the songlike quality in poetry, it is more generally used to refer to any short poem that expresses a personal emotion, be it a sonnet, ode, song, or elegy.
In ancient Greece, a poem was accompanied by a musical instrument, usually a lyre, hence the word 'lyric.'
