      German Wikipedia says:

      Herkunft:

von mittelhochdeutsch ‚tief’, althochdeutsch ‚tiof’ aus germanisch ‚*deupa-’, indoeuropäisch ‚*dheub-, *dheup- „tief, hohl“. Das Wort ist seit dem 8. Jahrhundert belegt.^[1]

English Wikipedia says:

From Middle English depe, deep, dep, deop, from Old English dēop (“deep, profound; awful, mysterious; heinous; serious, solemn, earnest; extreme, great”), from Proto-Germanic *deupaz (“deep”), from Proto-Indo-European *dʰewbʰ-nós, from *dʰewb- (“deep”). Cognate with Scots depe (“deep”), Saterland Frisian djoop (“deep”), West Frisian djip (“deep”), Low German deep (“deep”), Dutch diep (“deep”), German tief (“deep”), Danish dyb (“deep”), Norwegian Bokmål dyp (“deep”), Norwegian Nynorsk and Swedish djup (“deep”), Icelandic djúpur (“deep”), Lithuanian dubùs (“deep, hollow”), Albanian det (“sea”), Welsh dwfn (“deep”).

I say:

The modern Turkish word "dip" is very similar to these words. (Nisanyan verifies the age of this in 9. C, it could be much older) 

The older/other versions of this in other Turkish dialects like: tüp, dif, div, dip, düyp, tüb, tüf, tep, tib are all compatible (in Sound and Meaning) with the PIE root(s). Aren't they?

Look at the meanings of all these Turkish words above?

- Deep, Tief, Boden, Fundament, Base, Foundation, Root, Wurzel, Origin, Herkunft, etc...

And my sources say:

Prof. Dr. Gülensoy - Köken Bilgisi Sözlüğü

Eyuboglu - Türk Dilinin Etimolojik Sözlüğü

By the way Latin word depressa, too! (Like in Depression) and Turkish word dibek 

(English mortar/ German Mörser) could have a relation to that, at least figurative...
