Normally, in English we treat the verb to cry as intransitive, however in Latin it seems to be used transitively. For example:
Amissum non flet cum sola est Gellia patrem
She cries "at" her father. However, her father does not really seem to be truly the "object" of the verb, in the sense that her father is not acted upon, but is merely the object towards which the action is directed. So, should it be understood that a transitive verb can either act on its object or towards its object. Or rather should this sentence be considered a special use of the accusative case? For example, if we write ad patrem, then patrem is not an object of fleo at all.
I see in L&S that the verb fleo has a notation "v. a. and n." and it is not clear what this means to me. Active?
