FIT

in literature, a division of a poem or song, a canto, or a similar division. The word, which is archaic, is of Old English date and has an exact correspondent in Old Saxon fittea, an example of which occurs in the Latin preface of the Heliand. It probably represents figurative use of a common Germanic noun referring to the unraveled edge of a fabric. Lewis Carroll revived this archaic poetic division (perhaps to lend gravity) in the composition of his 132-verse nonsense poem The Hunting of the Snark (1876), beginning with Fit the First: The Landing and ending with Fit the Eighth: The Vanishing.
