I was observed this week and was told that an example of subordination that I gave was incorrect. My example was "I ate carrots because I was hungry." Was my feedback correct, is my example wrong? My understanding of subordination is that this is two clauses "I ate carrots" (main clause) and "because I was hungry" (subordinate - dependent on the main clause). My observer told me that "I ate carrots" and " I was hungry" are both stand alone clauses and therefore it is not subordination. Can someone kindly explain this to me?
