The study of the semileptonic B decays at BABAR is presented. The results shown include measurements of the moments of hadronic-mass and electron-energy of the decay B {yields} X{sub c}{ell}{nu}; a determination of the |V{sub cb}| CKM matrix element and other heavy quark parameters from a simultaneous fit to the moments using kinetic scheme of Operator Product Expansion; a measurement of the inclusive branching fraction of B {yields} X{sub u}{ell}{nu} and determination of |V{sub ub}|. The most recent BABAR search for the lepton flavor violating decays {tau} {yields} {ell}{ell}{ell} is presented as well.
