How to use prepositions with “cause”

“Cause” commonly combines with “of” and “for.” Other prepositions may appear depending on the sentence structure and meaning.

Quick answer

Common prepositions with “cause”

The standard patterns are “cause of” for origin and “cause for” for reason or justification. “Cause to” usually belongs to a verb pattern, while “without cause” and “about the cause” are separate expressions with different meanings.

These forms are not interchangeable. Choose the construction by meaning, not by which preposition appears most often.

1
cause of + result

Identifying the reason something happened

Use “of” to state the origin or reason for an effect.

Showing justification or grounds

Use “for” to express a reason for concern, celebration, action, or response.

Showing lack of justification

This fixed phrase means without a valid reason.

Talking or learning about a cause

“About” usually relates to discussion or knowledge, not directly to the noun “cause” itself.
