[1] _vocare_ helps to form several phrases—e.g. _in invidiam, in
suspicionem, in dubium, ad exitium, in periculum vocare_. It is used
in the passive to express periphrastically the passive of verbs which
have only an active voice—e.g. _in invidiam vocari_, to become
unpopular, be hated, _invideor_ not being used. Cf. _in invidiam
venire_.
