I discovered today that there is a connection between the Gaelic word for knowledge, information, news – fios in Irish and Scottish Gaelic, fys in Manx – and the English words video and wit.
Their roots can all be traced back to the Proto-Indo-European root woid-/wid- (to see/to know), which, according to the OED, is also the root of words such as the Sanskrit वेदा (veda – knowledge); the Latin vidēre to see); the Welsh gwybod (to know); the Lithuanian véidas (face); and the Greek ἰνδάλλεσθαι (to appear).
The Irish and Scottish Gaelic word fios is also related to the word fionn (white, fair, pale; sincere, true, certain; small; fine, pleasant), which is how I discovered this while putting together a new page of Scottish Gaelic colours – you can see how easily I get distracted. This doesn’t worry me as it’s all very interesting.
