Extended affine Weyl groups are the Weyl groups of root systems of a new class of Lie algebras called extended affine Lie algebras. In this paper we show that a Ε½ . reduced extended affine Weyl group is the homomorphic image of some indefinite KacαMoody Weyl group where the homomorphism and its kern
