Prepositions after verbs

Disrupt by, in, for, through or after?

Disrupt usually takes a direct object without a fixed preposition. The prepositions by, in, for, through, and after often introduce cause, place, method, or time instead.

Quick answer

How is disrupt used with prepositions?

Disrupt normally appears as disrupt + object, such as disrupt traffic or disrupt operations. Prepositions like by, through, in, for, and after are usually separate parts of the sentence rather than fixed combinations with the verb.

The storm disrupted flights across Europe.
Service was disrupted by a power failure.
The hackers disrupted communication systems.

Some combinations appear in real text but do not mean what learners often assume.

Treating for as a fixed pattern

Using in instead of a direct object
