Mastering the Adverbial clause of cause (Misplaced Words) is essential for advanced English grammar and correct sentence structure. An adverbial clause of cause explains why something happens, but placing it incorrectly in a sentence can severely disrupt your writing clarity.
What is an Adverbial Clause of Cause?
An adverbial clause of cause is a dependent clause that functions as an adverb to tell us the reason for the action in the main or Principal clause. These clauses can generally be placed either before or after the principal clause without changing the core meaning.
Consider these standard, correct English grammar examples:
- As he was ill, he could not go there. (Clause placed before the principal clause)
- He wears torn clothes, because he is poor. (Clause placed after the principal clause)

How to Express Cause Differently in English Sentences
Sometimes, a reason or cause is expressed using specialized structural patterns rather than standard subordinating conjunctions like because or as. Take a close look at these two correct sentences:
- This is the reason why he failed his exam.
- It is because of his illness that he could not attend the party.
Common Mistakes to Avoid with Misplaced Cause Clauses
A major grammar mistake occurs when writers try to move these specific causal clauses to the front of the sentence. Unlike standard subordinate clauses, these fixed patterns cannot be front-shifted.
| Incorrect Structure (Wrong) | Grammatical Explanation |
|---|---|
| Why he failed his exam this is the reason. | Never move a relative cause-focus clause to the beginning of the sentence. |
| That he could not attend the party it is because of his illness. | Creates a double-subject error and completely violates English syntax. |
Key Takeaways
- Standard adverbial clauses of cause (using as, because) are flexible and can appear before or after the Principal clause.
- Special causal structures like "This is the reason why..." must remain in their standard positions.
- Front-shifting fixed causal clauses results in severe misplaced words and ungrammatical sentences.
