However, you can use "except" in a compound sentence by incorporating it into a phrase that modifies one of the clauses. Here are a few examples:
1. Using a phrase with "except" as a modifier:
* The children played outside all afternoon, except for when it started to rain. (Here, "except for when it started to rain" modifies the first clause.)
2. Using a dependent clause with "except" as a conjunction:
* We enjoyed the trip, except that the weather was awful. (Here, "except that the weather was awful" is a dependent clause modifying the first clause.)
3. Using "except" in a parenthetical phrase:
* The entire team was invited, except for the coach (he was busy with other commitments). (Here, "except for the coach" is a parenthetical phrase modifying the first clause.)
Important Note: When using "except" in these ways, be sure to maintain correct sentence structure and punctuation. You might need to use commas or other punctuation to separate the clauses and phrases.
