The poetic device that is not used in line 3 of "The Raven" by Edgar Allan Poe is External rhyme.
Explanation:
The line 3 in "The Raven" by Edgar Allan Poe is "While I nodded, nearly napping, suddenly there came a tapping" and here we have the use of internal rhyme with the words "napping" and tapping", then there is the use of alliteration with the repeated sound of the consonant "n" in "nodded", "nearly" and "napping".
