Motivated by recent experimental results we reconsider semileptonic D {yields} Plvl and D {yields} Vlvl decays within a model which combines heavy quark symmetry and properties of the chiral Lagrangian. Using limits of soft collinear effective theory and heavy quark effective theory we parametrize the semileptonic form factors. We include excited charm meson states in our Lagrangians and determine their impact on the charm meson semileptonic form factors. Then we calculate branching ratios for all D {yields} Plvl and D {yields} Vlvl decays.
