Substratum lexicon in Indo-European

Dear Members!

Thank you all who joined this list. I am sure this idea will be a
success of Indo-European studies online!

I'm now gathering info about substratum words in Indo-European
languages for a new project on CyBaLiSt. I have already found something
very interesting about Germanic, Greek and Celtic, but I'm sure other
branches also contain lexicon which was spoken in Europe and Asia long
before Indo-Europeans came.

I would appreciate if you can share your knowledge on the matter.

Cyril
