(103) some(x, mouse(x), def(y, table(y), appear(e 1 , x) ∧ from(e 2 , e 1 , e 3 ) ∧ under(e 3 , u, y))) On this analysis, the first preposition from is transitive, and it takes the PP under the table, or rather the event introduced by this preposition, as an argument.
to ERG, this analysis allows the last argument of a preposition like from to be an event, e 3 , as well as an individual.
