What is the Greek root in English?

There isn't one single Greek root for the word "English". The word "English" itself has a Germanic origin, coming from the Anglo-Saxon word "Englisc", which ultimately derives from the name of the Angles, one of the Germanic tribes that settled in Britain.

However, many English words do have Greek roots. Here are a few examples:

* -graph (meaning "write" or "drawing"): autograph, photograph, telegraph

* -logy (meaning "study of"): biology, geology, psychology

* -meter (meaning "measure"): thermometer, barometer, speedometer

* -phone (meaning "sound"): telephone, microphone, symphony
