This is #16 in my never ending series on English as I learned it growing up.
Today we'll examine a secondary usage of the word "might". Here's a good example from a song called "The Devil's Right Hand" by Steve Earle:
"....shoots as fast as lighting but she loads a might slow........."
The song is in reference to a pistol, and the complaint is that it's hard to load, so it has its limitations in a gun fight. Just so you know.
That is a tried & true, honorable, and (to me and mine) a very familiar usage of the word "might". You could have said "it loads a bit slowly", or "a little slow", and you would have expressed an idea in the same general realm, but would not be the same.
The usage of "might" this way almost always include an "a" before it, and more importantly, the usage is almost always an understatement, irony or out right sarcasm, used to make a point.
If someone describes someone as "a might peckish...." that would be a good person to avoid, either on a specific topic or in general, depending on the context. Unless you seek out conflict.
Maybe I'll discuss peckish later.
