This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The historical origin of 祋 is uncertain. It combines 示 (altar, spirit) with 殳 (a weapon or action), but the exact development is unclear.
With no clear meaning, focus on the shape: an altar 示 beside a weapon 殳. Imagine a ritual object or a ceremonial weapon, but treat the meaning as unknown.
For タイ, imagine tying a ceremonial cloth to the altar-weapon: tie -> タイ, linking the shape to the sound.
