In case of a bipolar junction transistor, we have only three terminals (legs). They are emitter, base and collector. But, in case of a MOSFET (metal oxide semiconductor field effect transistor), we can have four legs. They are source, drain, gate and substrate. The substrate is not being shown in some notations of MOSFET. But it does exist. Hence, a MOSFET has four legs.
