An effective Lagrangian that describes the low-momentum interactions of mesons containing a heavy quark with the pseudo Goldstone bosons {pi}, {ital K}, and {eta} is constructed. It is invariant under both heavy-quark spin symmetry and chiral SU(3){sub {ital L}}{times}SU(3){sub {ital R}} symmetry. Implications for semileptonic {ital B} and {ital D} decays are discussed.
