Here's why that's important:
* Structure: Couplets (two-line stanzas with rhyming lines) give the poem a distinct rhythm and flow.
* Accessibility: The regular rhyme scheme makes the poem easier to read and remember, even though it's written in Middle English.
* Oral Performance: Chaucer intended the tales to be read aloud, and couplets are well-suited for oral performance.
So, when you're reading The Canterbury Tales, keep an eye out for those rhyming pairs!
