Sound Device
Slant Rhyme
Dickinson made slant rhyme her signature; Wilfred Owen used 'pararhyme' (consonance-based) for deliberate unease in World War I poetry. Now common in all contemporary verse.
Definition
An approximate rhyme in which sounds are similar but not identical — also called half rhyme, near rhyme, or pararhyme.
