The Category P Features, Projections, Interpretation

145
The entry in (i) corresponds to the occurrence of run with a locative adjunct, which
is not part of the verbal theta-grid. (ii) is the theta-grid of the Directional run. As
mentioned earlier, unlike the locative PP, the Directional phrase can occur only with
path denoting verbs, and therefore it is part of the theta-grid of the verb.
It is standardly assumed that an Agent theta-role is mapped externally, whereas the
Theme and Goal theta-roles are mapped internally (see Reinhart 2000, 2001 for the
precise formulation). Thus the (Directional) run in (ii) is clearly unaccusative, as it does
not have an external theta-role. Crucially, Reinhart claims that the mapping
generalizations apply only to n>1-place verbs, namely, they do not apply to one-place
entries. The argument of a one-place verb, regardless of its thematic specification, maps
externally. Therefore run in (i) is unergative, even though it assigns a Theme rather than
an Agent.
4.3.4 On a certain distinction between Goal and Source Directional PPs
Although the Source PP headed by from is commonly assumed to be a Directional
PP, it does not behave identically to the Goal PP headed by a P such as to. Consider the
examples in (63):
(63) a. ha-tiyul me-/le-hodu nimšax šavu’a
the-trip from-/to-India continued week
“The trip from/to India took a week.”
b. dan barax me-/el ha-kfar
Dan escaped from-/to the-village
“Dan escaped from/to the village.”
c. ha-yeladim me-/*le-hodu nir’u ayefim
the-children from-/to-India looked tired
“The children from/*to India looked tired.”
Similarly to the Directional Goal PP, the Source PP combines with path
denoting heads (63a,b), and the P me- (‘form’) defines its complement as the initial
location of an entity moving along a path. However, unlike the Goal PP, Source PP
headed by me- (‘from’) is not limited to this particular group of heads. In its additional
