Q: I’m a reporter in the Midwest. The other day I did a story about local people in the military. I wanted to say the term “GI” is short for “government issue,” but the copy editor insisted it’s an abbreviation of “galvanized iron.” In the end, we took it out. Who’s right?
A: Both of you, depending on how the abbreviation is used. Here’s the story.
In the early 20th century, “GI” was a semiofficial US Army abbreviation for “galvanized iron.”
The term, dating back to 1907, was used in military inventories to describe iron cans, buckets, and so on, according to the Random House Historical Dictionary of American Slang.
By 1917, however, “GI” began to take on a wider meaning.
In World War I, it was used to refer to all things Army, so military bricks became GI bricks and military Christmases became GI Christmases. Before long, we had GI soap and GI shoes and, eventually, plain old GIs.
A lot of people apparently felt this new usage needed a new family tree. So in the minds of many, “galvanized iron” became “government issue” or “general issue.”
The Oxford English Dictionary says “GI” can be an abbreviation for all three, depending on how it’s used:
It stands for “galvanized iron” when used in a phrase like “GI can” (an iron trash can or a World War I German artillery shell). It’s short for “government issue” or “general issue” when referring to American soldiers or things associated with them.
The American Heritage Dictionary of the English Language (4th ed.) and Merriam-Webster’s Collegiate Dictionary (11th ed.) list only “galvanized iron” and “government issue” as the longer forms of “GI.”
The entry for “GI” in American Heritage sums up the etymology this way: “From abbreviation of galvanized iron (applied to trash cans, etc.), later reinterpreted as government issue.”
