In "The Raven", which rhyming words are repeated often troughout the poem, and which two lines in each stanza do not contain end rhyme?rhyme

Rhyming
words:

• Rapping, tapping,
  napping


• Lenore, Nevermore, bore, yore, o'er, explore,
  before, door...

The 1st and 3rd lines or the a
and c lines regularly do not have end rhyme because they generally have internal rhyme.
This means there is a word within the line that rhymes with the end
word.

The effect of the rhyme scheme in this poem is a
fantastic rhythm that helps move the reader from stanza to stanza with intensifying mood
and even plot development.
