What is the name for the pattern of rhyming words at the end of each line in a poem?

Answer 1

The pattern of rhyming words at the end of each line in a poem is called a "rhyme scheme." Rhyme schemes are typically described using letters to represent the sounds at the ends of the lines; for example, in an "AABB" rhyme scheme, the first two lines rhyme with each other, and the next two lines rhyme with each other.
