A <goldstino> is the massless spin-one-half mode associated with spontaneously broken global <supersymmetry>. For <F-term> breaking, the <fermion> in a multiplet with nonzero <auxiliary field> transforms by an inhomogeneous term, $\delta G\supset\sqrt2\epsilon F$. In <supergravity>, the corresponding mode supplies the longitudinal degrees of freedom of a massive gravitino.
