The unnormalized <Jacquet module> is the space of coinvariants of a unipotent subgroup $U$. If a subgroup $T$ normalizes $U$, it acts on this quotient. Every <linear functional> transforming by a <linear character> trivial on $U$ factors through it. Normalized Jacquet functors include an additional modulus twist; that convention must be specified.
