noun
Historical title for the wife of a crown prince in East Asian monarchies; not used in modern contexts.
王太妃は、王太子の妃として宮中で重要な役割を担った。
The crown princess played an important role in the court as the consort of the crown prince.
A queen consort or princess consort; 王太妃 specifically denotes the wife of a crown prince, not the reigning king.
