Now is this "turn" as in "gaeth y car tro i'r chwith" or is it like "mae'n dy dro i rolio'r dis?"
Tro (noun) - a turn, twist, bend, go, etc, as in a turn in a game, a bend in a road, a turning, a walk.
Troi (verb-noun) - to turn/twist, turning/twisting.
Look for examples in www.gweiadur.com and www.geiriaduracademi.com
"a walk" was not accepted - could you add it please?
(I had been thinking of mynd am dro.)
