With our current knowledge of syntax, we would diagram it as so: + +![`[T [D Alice] [T_D [T_{D,V} will] [V [V_P speak] [P [P_D to] [D [D_N the] [N assembly]]]]]]`](no-subject-movement.png) +<details markdown="block"> +<summary>LaTeX</summary> + +```forest +\begin{forest} + [$T$ + [$D$ [Alice, roof]] + [$T_D$ + [$T_{D,V}$ [will, roof]] + [$V$ + [$V_P$ [speak]] + [$P$ + [$P_D$ [to]] + [$D$ + [$D_N$ [the]] + [$N$ [assembly]]]]]]] +\end{forest} +``` + +</details> + +The $D$ *Alice* here is the subject. While replacing it with some $D$s produces grammatical sentences ex. *The prime minister will speak to the assembly*: this is not true of all $D$s. Slotting in inanimate $D$s like *Time will speak to the assembly* and *Knowledge will speak to the assembly* produces grammatically unacceptable sentences. So there is some *selection* occurring somewhere in the sentence that wants a particular *feature set* (f-features) from the subject $D$. + +Observe, however, that our tree structure suggests that $T$ - and only $T$ - is involved in the selection of $Alice$ as the subject, given locality of selection. But this can't be quite right. Plenty of other sentences involving the $T$ *will* are just fine with inanimate subjects: *Time will pass*, *Knowledge will be passed on*, etc. (Notice that *Alice will pass* and *Alice will be passed on* are similarly ungrammatical). How do we reconcile this? + +We now introduce the idea of $vP$ shells and V-to-T movement. Our observations above point towards the $V$ of the sentence rather than the $T$ selecting for the subject $D$ - somehow. This selection would break our guiding principle of locality of selection. But this behavior *does* occur. Can we extend our model to explain this, *without* modifying the locality of selection that has been so useful thus far? We can, indeed, and illustrate so in the following tree. + +![`[T [D Alice] [T_D [T_{D,V} will] [V [D (subj)] [V_D [V_{D,P} speak] [P [P_D to] [D [D_N the] [N assembly]]]]]]]`](subject-movement.png) +<details markdown="block"> +<summary>LaTeX</summary> + +```forest +\begin{forest} + [$T$ + [$D$ [Alice, roof, name=Alice]] + [$T_D$ + [$T_{D,V}$ [will, roof]] + [$V$ + [$D$ [(subj), roof, name=subj]] + [$V_D$ + [$V_{D,P}$ [speak]] + [$P$ + [$P_D$ [to]] + [$D$ + [$D_N$ [the]] + [$N$ [assembly]]]]]]]] + \draw[->,draw opacity=0.5] (subj) to[out=west,in=south] (Alice); +\end{forest} +``` + +</details> + +So we say that *Alice* is originally selected by the $V$ and *moves* to its surface position in the $T$. Our head movement principles allow for this. This does mean that every tree diagram we have drawn up until now is inaccurate, and that almost every tree we draw going forward will have to have this V-to-T movement.
