We give a root multiplicity formula for all the roots of almost hyperbolic Kac-Moody algebras \(H A_{n}^{(1)}\). We use the path realization of crystal bases for the irreducible highest weight modules over quantum affine Lie algebras \(U_{q}\left(A_{n}^{(1)}\right)\) to determine the root multiplici
