As'so-nance, n.

n. [Fr. assonance. See infra.]

1. Resemblance of sounds. “The disagreeable assonance of ‘sheath’ and ‘sheathed’.” Steevens.
2. (Pros.) A peculiar species of rhyme, consisting in the correspondence of the last accented vowel and of those which follow it with the vowels of another word, while the consonants of the two words have no correspondence, or not a perfect correspondence, with each other; as, calamo and platano, ligera and tierra, baby and chary.

The assonance is peculiar to the Spaniard. Hallam.
