What is telescopic split into a root word prefix and suffix?

The word "telescopic" doesn't have a clear root word, prefix, or suffix in the traditional sense. It's formed directly from the word "telescope", which itself is a combination of Greek words:

* tele - meaning "far" or "distant"

* skopein - meaning "to look" or "to view"
