What type of sentence would this be consider as. I ate dinner when got home. a complex or simple sentence?

Here's why:

* Complex sentences have one independent clause (a complete thought that can stand alone) and at least one dependent clause (a thought that cannot stand alone).

* Independent clause: "I ate dinner"

* Dependent clause: "when I got home" (This clause depends on the independent clause to make sense.)

The dependent clause is introduced by the subordinating conjunction "when".
