Δρύ-ς > Dru > Tree

the Druide & the TreeΔρυς (drys = oak) was  the most sacred of all trees and its worship was popoular in ancient Europe. Τhe Druid or Drouide (Δρυίδης – Δρουίδης) was the priest.

In many European languages, Eastern and Western, they name the tree like this:
drv-oa in slavic, derwen in welsh, drusk in albanian and of course δένδρο (dendro) in greek.

The dental consonant δ (d), from medium becomes high (t). The vowel υ (yu) is transformed into ee and makes the English tree. In protogermanic is trewan and in gothic triu.

When the letters u and r changed position, from oak (dru) comes the latin dur-us to mean hard because the tree is a symbol of strength and hardness! The word returns in Greek and when someone is strong and standing up, we say that he is ντούρος (ntouros-douros)!
