I'm learning Greek so I can 1) read the Bible and 2) to learn english better... because as you said a lot of english words come from Greek words. By the way, same thing with Latin (I'm learning that also), a lot of english words have Latin roots.
so the first word starts with "th"? I thought that was a capital delta? and isn't than an omega at the end (second to last letter) of the second word? In which case it would be a long O at the end? You'll have to excuse if I screw up... I'm learning old style greek, not very widely used today.
