I was guessing in this direction. This is the way/wagon root. EIEC
(under "Road") gives 'capable of carrying passengers' as one sense,
but this is not quite 'convey in a vehicle'. They give Old Indic
vahyá as the cognate. EIEC, it should be noted, marks this entry with
a question mark, indicating some doubt. It is suggested the western
and eastern words are independent coinages.
