What term describes lines rhymed by their final two syllables?

The term that describes lines rhymed by their final two syllables is feminine rhyme. This type of rhyme occurs when the last two syllables of the rhyming words correspond in sound, creating a softer or more flowing effect within the poem. Feminine rhymes typically involve an unstressed syllable followed by a stressed syllable, which contributes to the musicality and rhythm of the verse.

In contrast, masculine rhyme refers to rhymes that occur at the final syllable of the words, creating a more emphatic and strong ending. Assonance involves the repetition of vowel sounds in nearby words, while consonance focuses on the repetition of consonant sounds. These terms describe different sound patterns and do not relate to the specific structure of rhyming lines by their final two syllables, which is why feminine rhyme is the correct designation in this context.
