People who have studied languages and literature can relate that most don’t understand what’s so fascinating about either of those things. In fact, they end up calling us the grammar police and that’s about it.

But when linguists start talking about etymologies—the origins of words—it’s quite often the case that non-linguists start showing massive interest in it, mostly because things begin making sense in their brains so much that they become giddy with such knowledge and they start to understand just how intricate, logical, and simply interesting language really is.

This kind of situation happened recently when Twitter user Benjamin Molineaux found out the original meaning of upper case and lower case. This was not only absolutely fascinating to others, but also prompted some people to share their own tidbits of etymological knowledge.

You’d be surprised to learn how many words sound a bit odd, but have very logical origins

So, it all started with Twitter user Benjamin Molineaux posting a picture of a pair of printer’s cases (as illustrated in a book of some sort).

Jokingly, he said that kids today are surprised to learn that the save icon is actually a 3.5-inch floppy disk—because that’s where we used to save a lot of our digital things before all these terabytes we don’t know what to do with nowadays—and he, today, is surprised to learn that upper and lower case refers to actual cases, boxes.

These were used in old printing presses, with one part of the box containing all of the capitalized letters and the other having the non-capitalized ones. One is, hence, the upper case, the other is the lower case.

It all started off with one user explaining the origins of upper– and lowercase letters

This led to a number of people sharing similar typography-related terms and providing their etymologies, further blowing the minds of other tweeters.

And it lead to many others explaining the origins of other typographical terms and icon

For instance, the word font has a common root with found and hence foundry, referring to how olden printing used to be done. Also, leading refers to the size of the lead strips used to create the spaces that lead the type.

Another lesser-known fact is that keyboards now have a shift key, which refers to the action of shifting the entire type bar on typewriters between upper and lowercase characters.

Needless to say, the terms cutting and pasting, while still being used today, refer to actual cutting of the printed text using scissors and pasting it using glue as part of the editing process.

Everything from fonts and foundries to leading and copy/pasting were mentioned in the thread
