Final answer:
Lines 9-12 in 'The Raven' convey the speaker's deep sorrow over Lenore's loss, indicating she has passed away and was dearly loved, contributing to the poem's mournful tone.
Step-by-step explanation:
The lines 9-12 from The Raven by Edgar Allan Poe imply a deep sense of sorrow and loss for Lenore, whom the speaker mourns. The mention of the "lost Lenore" suggests that she is deceased, which explains her absence. The phrase "For the rare and radiant maiden whom the angels named Lenore" indicates that Lenore was a beloved figure to the speaker and her brightness and rarity continue to affect him deeply, setting a melancholic and mournful tone for the poem.
