Something which coggles usually has a rounded base. If coggles too violently then it can be coggled over, or overturned.
Things which don't stand too firmly on their bases can even be coggly.
The word coggle is, plainly, completely charming, and it has been drafted in for other uses. A coggle is a wheel used for making small dents or grooves along the edge of plates before they are fired (though why anyone should wish to do this I have no idea at all).
A coggle can also be another word for the sort of cobble that's used to make a path or road; or a coggle can be a small boat (which coggles along if the sea is rough); or it can even be a way of drawing word-trees on a computer.
In fact, you know something? It makes standing up straight seem really rather overrated.
Thing Not To Do Today: coggle. The origin of this word isn't known, but could be something to do with the type of coggle/cobble which tends to tip you off-balance when you tread on it. On the other hand it might be a diminutive of cob, a small boat. Or the word may have come about just because it sounds such fun, as did the word joggle.
