This Connect Wall is pretty straightforward (?), but I thought it might be a fun mini-puzzle!
Connect Wall rules: Divide these sixteen words into four groups based on something they have in common. You'll find that the four groups have something in common themselves. The words aren't in any particular order.
DACTYL, WARDED, BASHED, PEDAL, CYCLE, HANDLE, CAKE, CORN, GRAPH, ESTER, MATH, WAKE, TRIES, FRIED, POLAR, BRIDGE
