Origin of guru
- Hindi guru from Sanskrit guruḥ from guru- heavy gwerə-1 in Indo-European roots
From American Heritage Dictionary of the English Language, 5th Edition
- From Hindi गुरू (guru) / Urdu گرو (guru), from Sanskrit गुरु (gurú, “venerable, respectable”), originally "heavy" and in this sense cognate to English grieve. (A traditional etymology based on the Advaya Taraka Upanishad (line 16) describes the syllables gu as 'darkness' and ru as 'destroyer', thus meaning "one who destroys/dispels darkness")
