Adding information about the causes of actions and events

page 3 of 5

The first verb provides information about the prevention of the main action:

The Government should stop private schools from collecting an entire year's fees at once.

Here are some "prevention" verbs commonly used in double-verb structures:

avoid ban bar deter discourage disqualify forbid * gag keep prevent prohibit relieve restrain save stop

* Note that with the exception of forbid (which is typically followed by the to-infinitive ), there is a tendency for "prevention" verbs to be followed by the preposition from followed by the -ing form. However, there are some exceptions: stop and prevent are both more commonly used without from; avoid is never used with from.
