Because it was raining ,we cancelled the trip. The trip was cancelled____ _the rain
The trip was cancelled because of the rain.
The preposition “because of” is used to indicate that one event is the cause of another. In this case, the rain is the cause of the trip cancellation.
The phrase “due to” can also be used to indicate cause, but it is more formal and less commonly used in spoken English.
Here is an example of how the phrase “due to” could be used in a similar sentence:
The trip was cancelled due to inclement weather.
However, the phrase “because of” is more natural and idiomatic in this context.
