to gaze at
眙 centers on fixing one's eyes on something: gazing intently or staring.
眙 combines 目 (eye) with 台, which likely contributes the sound. The character is not common in modern Japanese, and its precise historical development is uncertain.
The left side is an eye 目, and the right side 台 looks like a platform. Imagine an eye fixed on a platform, gazing intently at something placed there.
For チ, picture a tiny cheese on the platform, and your eye gazes at it: cheese -> チ, and you stare at the cheese.
