The Etymon 'Vithu'
The word'Veda' is derived from Tamil word 'Vithu'(வித்து ) which means 'seed' This word is derived fro verb 'Vithai' which means 'to seed' One who sows 'knowledge' is 'Vithuvan'(வித்வான் ) which means 'expert' in Tamil.'Vitham' is 'variety' in Tamil.''Vindhu' is 'semen' in Tamil.

Etymology Of Sanskrit Word 'Puja'

 The Sanskrit word ‘Puj’ and Tamil word ‘Pusai’ are considered cognate words.While in Sanskrit the word is a morpheme (vide page 641 of Sanskrit-English ,Dictionary-Monier Williams), in Tamil the word ‘Pusai’ breaks down into “Poo+sei’.’Poo’ is ‘flower’ and ‘Sei’ is ‘to do’.The ritual ceremony done with flowers to God , is thus called ‘Pusai’in Tamil.In contrast ‘Puj’ in Sanskrit means ‘to honour,to worship’and this inference has no basis. If cognate words in two languages X and Y are morphemes, the conclusion of cognation stands beyond question.But in case the word could be broken down further in X language, the probability of that word belonging to X language is certain.Hence the etymology of Sanskrit word 'Puja' is Tamil word 'Pusai' only.
 The supporting collateral words in Tamil are 'Poosari'(Priest) ,Pookary(flower seller) ,Poopu(Puberty) ,Poo malai (flower garland) ,Poo chorithal(flower shower) etc.
Sanskrit does not have these supporting words.

Etymology of the Hindi word ‘Guru’

                                 The Hindi word ‘Guru’ is believed to be derived from Sanskrit.  Wiktionary says that it is 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)^[1]describes the syllables gu as 'darkness' and ru as 'destroyer', thus meaning "one who destroys/dispels darkness

                             Now we may examine both views in depth. If both views are correct, we should be able to find other Sanskrit words containing ‘gu’ for ‘darkness’ or ru for ‘destroyer’.Similarly we find no supporting words for ‘heavy’ also either in Sanskrit or Hindi.

           The Tamil word ‘kuru’ means ‘small particles’ and is extensively used in everyday usage.”Kuru man’(குருமண் )means’fine sand’ and this word is cognate to Greek ‘krume’ and English’gravel’. Ear wax is called ‘Kathu Kurumi’.’Kurunai ’ is ‘small broken pieces of rice’ in TL.Prickly heat blisters are called ‘Ver Kuru’ in TL.’Kurugia’ is ‘small’ used in the sense of ‘narrow’. ‘Kuruni’ is a measure of a small piece of land.‘Kuru mannar’ is a King for small territory.

                               ‘Kuru’in TL also takes an extended meaning of’minute ie,very small’.Thus ‘Kurunathan’ a common Tamil name ,means ‘Master of any subject, who knows it to the minute level’. So teacher is called a ‘Kuru’ shortened form of‘Kurunathan’This TL word  got into Sanskrit and became’Guru’in Sanskrit.  

                    Apart from the clear meaning,  the presence of ample no of supporting words in Tamil indicates that the most probable and acceptable root for ‘Guru’ is Tamil ‘Kuru’(குரு )  only.The presently accepted view mentioned above cannot be correct in the absence of any supporting evidence.
