You know if you are anywhere near being a 'reader' your eyes probably 'dance' over words or letters that you really don't have a clue how they came to be.
Well some years ago I developed an interest in the history of works or 'letters' such as "G.I." wondering....now just where did this come from. Well Mr. Reader you would be very surprised....and I'm just talking about "one" set of letters or words.
So...since my interest or 'hobby if you will' is nautical or military, try wrapping your mind around this.
Why Do We Say "G.I"
