Thanks! I’ve never seen those before, so no wonder I was confused 
In German, ß is an etset, used as a shorthand for double s. The word for “white” can be spelled either weiß or weiss.
You know the fog you see that comes out of a hot shower?
Or the fog that rises from a pot of boiling water?
Everyone calls it “steam.”
It is not steam! Steam is invisible. If you can see it, it ain’t steam!
It is a mist… 
George Carlin said it was called a “der-der,” because when you were a kid, you ran around the house with one up to your mouth like a horn, and sang “der-der-der-der-der” into it. So that’s what I call them.
Another anatomical tidbit: That little piece on the inside part of your ear that sticks out toward the auditory canal (and where hair grows after you turn forty) is the tragus.
When you’re waiting in line, and there are posts holding up chain or webbing or velvet rope - those posts are called “stanchions.”
If there’s a fancy top on a post, that’s a “finial.”
The symbol ~ is called a “little squiggly thing.”
Escutchen is not specific to the plumbing application. Doorknobs are typically surrounded by an escutchen where they come out of a door. Though not commonly heard, escutchen or excutchen plate is a correct term for the outer plate on an electrical outlet or wall switch.
A ferrule is any kind of ring, cap or cover, usually metallic, on a handle, tool or similar object used to strengthen, prevent splitting, or attach other objects. For example, the term can also be applied to the metal part that attaches brush hairs to a brush handle.

I see people have already cited my favorite “body parts you never knew had names”, the glabella and the tragus. Here’s another one: Hold out your hand, palm down, and extend your thumb fully (as though hitchhiking, but keeping your fingers straight). See a small hollow space just above your wrist, between the two tendons running down from your thumb? That’s the anatomical snuff box.
(Why snuff box? Because it was used for snuff-snorting purposes back when snuff was common.)
The “~” or squibble or sort-of dash to the left of the “1” key on a “QWERTY” keyboard is called a TILDAY. According to wikipedia it has so many different uses in everything from spanish language scribes using it as a notation of abbreavation, to what I know it for as MICROSOFT file format notation scheme when it extended the FAT file system standard to support long filenames for Microsoft Windows. Programs written prior to this development could only access filenames in the so-called 8.3 format—the filenames consisted of a maximum of eight characters from a restricted character set (e.g. no spaces), followed by a period, followed by three more characters. In order to permit these legacy programs to access files in the FAT file system, each file had to be given two names—one long, more descriptive one, and one that conformed to the 8.3 format. This was accomplished with a name-mangling scheme in which the first six characters of the filename are followed by a tilde and a digit. For example, “Program Files” might become “PROGRA~1” (per wikipedia)
Now did you know that the collective noun for a group of Crows is called a MURDER. :smack:
It’s spelled “tilde”.
A very old thread to which no one has posted for some time (maybe even years) and has been suddenly revived by a new post is called a “zombie”.
It may now, but I first heard it used long before I ever heard of ethernet. In the 1980s one of the ways that software was copy protected was to provide a hardware device that plugged into a certain port on your PC and the software would not run without that dongle.
One of my favorite words is finial. It can refer to the thing that you screw down to hold a lampshade in place or to the topping of the last post in a bannister.
A plectrum is a guitar or banjo pick.
Are you sure the / is a virgule? It is the French word for a comma. & is the ampersand and @ is the apparsat although it has many names. - is a hyphen, not to be coonfused with the endash (which is longer) or the emdash, aka dash, which is much longer. The endash should be used in numerical ranges: e.g. 2–4, while the dash is grammatical. The Ç is just a C cedilla. The ¥ is just yen. The thing that looks like a beta is an es-zet, while the last one on your list is just a Sigma (or perhaps a summation sign in mathematics).
Other things (besides animals) also called a frog:
The loop-and-knot fasteners on some old-timey jackets and at the neck of some capes.
The leather straps that hold a sword’s scabbard to a belt.
The spikey or perforated things used to keep flower arrangements in place.
The spikes on a Stegosaurus’ tail are called “thagomizers”, after the late Thag Simmons.
It there a name for the cross on small t’s?
Also, aglets can be found at the end or other kinds of laces, too. Corset laces, for instance. Aglets may or may not have predated shoe laces. Originally, they were made out of metal.
Apologies to OP- I asked for this to be removed as OT (stegosauruseses not being common and all).
The act of raising your shoulders in response to cold weather is called a hurple.
Kerf. The width of a saw blade cut. And yes, you do need to take it into account when you measure. And not just for fine cabinet work.
