Apologies to the teacher whom I am quoting but this is a genuine enquiry and I didn't want to put it on the original thread as I didn't want to interrupt the train of thought there. I am not criticising your use of English in any way here as I just think that's rude. Is it correct to say, "Hence why I am concerned"? My understanding of "hence" is "therefore". Would one say, "Therefore, why I am concerned" or just "Therefore, I am concerned"? Should it be "Hence, I am concerned"? I often here the phrase "hence why" and it sounds wrong to me.
