Thanks for the welcome, Jackie.

To finish the glass of vodka here's a bit of lecture:

Both Gaelic and Russian languages came from the same root - the Indo-European. Gaelic was one of the first Romance dialects whereas Russian is much younger and derives from a common Slavonic dialect, now extinct (just like Gaelic...). I would say that 'water' is one of the most basic concepts and therefore the need to name it had appeared long before the Indo-Europeans parted their talk. I suppose we could find the common origin of words for water from all the European languages save Finnish, Hungarian, and Basque (even French eau would qualify, though I cannot really believe it ).

Russian vodka is indeed a diminutive from voda - water - and is made from potatoes and/or rye. I prefer flavoured brands myself and I can recommend you all the famous 'Zubrowka' (exported as Polish Bison Vodka), best consumed with apple juice (mixed 1:3 - and that's 1 of vodka!).
