Iworked on the project until it was completed. identify the subordinate clause in the complex sentence. i worked on the project on the project it was completed until it was completed

The subordinate clause in the sentence is: it was completed.

Explanation: The main clause is "I worked on the project" and it is connected to the subordinate clause with the word "until". It is a subordinate (or dependent) clause because it would not make sense by itself, it depends on the main clause.

The subordinate clause in the complex sentence is "until it was completed".

Explanation: The sentence provided is a complex sentence because it is made up of an independent clause and a subordinate clause. An independent clause is a clause that can stand alone as a sentence, while a subordinate clause, which is introduced by a subordinating conjunction, cannot stand by itself because it does not express a full thought. In that way, "I worked on the project" is the independent clause in the sentence and "until it was completed" is the subordinate clause because it cannot stand alone and it is introduced by the subordinating conjunction "until".
