deceive
紿 centers on deception: misleading or tricking someone through false appearances or words.
紿 combines 糸 (thread) with 台, which likely contributes the sound. The thread component may relate to the idea of entangling or tying up in a deceptive scheme, but the exact historical development is uncertain.
The left side is thread 糸, and the right side is 台, which looks like a platform or stand. Imagine a thread tied around a platform to create a false appearance, like a stage prop meant to deceive.
For タイ, picture a deceptive tie (necktie) made of thread: tie -> タイ, and the thread 糸 is used to weave a lie.
