indistinct
眆 centers on visual indistinctness: something seen unclearly or without sharp definition. The single given meaning 'indistinct' is narrow, and the kanji is rare, so treat its core idea as unclear or blurred vision.
眆 combines 目 (eye) with 方, which likely contributes the sound. The exact historical development is uncertain, but the structure suggests a phono-semantic compound where 目 indicates vision and 方 hints at the reading.
The eye 目 looks at a square 方, but the edges are blurry and indistinct. Picture squinting at a fuzzy shape that you can't quite make out.
For ホウ, imagine trying to see a faint, indistinct glow (ほの.か) in the distance. The sound 'ho' from ほの.か can hook you to ホウ, as you strain your eyes to see the unclear light.
