hidden, unclear
瞹 centers on things that are not clearly seen or understood: something hidden from view or unclear in meaning.
瞹 combines 目 (eye) with 愛, which likely contributes the sound and the idea of something obscured or unclear. The exact historical development is uncertain.
The eye 目 looks at something, but the right side 愛 suggests a feeling of something being hidden or unclear, like trying to see through a fog of emotion.
For アイ, imagine an eye 目 trying to see through a thick fog, but all it can make out is a faint 'I' shape: I -> アイ, and the hidden object remains unclear.
