nm - double post
Ah, TIL.
I always thought it sounded pretentious, but figured that it had to have a more technical meaning, so thanks for providing it (with examples!). 
Hi Acsenray. Is there a chance your understanding of “signage” is mostly based on UK, rather than USA usage?
From the online Collins dictionary:
(American English) —
graphic designs, as symbols, emblems, or words, used esp. for identification or as a means of giving directions or warning.
The British English definition is essentially “Signs, considered collectively.”
A number of our Graphic Design students have gone on to jobs where they’re creating a lot of those “signs, considered collectively.”
One of them got a job designing museums (with a two-year Associates Degree from a technical college!), and another has been in charge of graphics for city parks, including a zoo. Both jobs include a lot of signs.
The zoo guy says his department refers to all the graphics, icons, and direction signs as “Wayfinding”.
I give him a hard time by calling it the “Hey, where am I, where are the Pygmy Marmosets, and how the hell do I get there and find a popsicle on the way?” Department.
But we both agree that Wayfinding has a less high-falutin’ name: Signage.
There’s a difference between “wayfinding” and signs like “do not feed the bears” and “no smoking”. Or “watch out for birds overhead”. Or the the “trash” and “recycling” signs on two halves of a large barrel receptacle. Or “Men” and “Women” at the restrooms.
Wayfinding is the current (IMO dumb) fancy term for directions. IOW, all things geo-referenceable. Not public safety, not compliance, and in the context of museums and zoos, not exposition about the exhibits.
Also allowed for those in the dental profession.
Wikipedia
Someone I know says “on tomorrow” or “on yesterday” like you would say “on Wednesday.” I don’t know where this usage comes from, but I don’t like it.
Your post is the first time I’ve ever heard this usage.
May I ask where roughly on Earth you are and is this usage heard in highbrow professional / academic arenas or more like down at the truck stop or bar?
If it’s just one person we’re probably safe from horror this unless that person is Oprah, Musk, or Trump. Those three seem to be pretty good at getting their speech idiosyncrasies popularized.
At the end of the day, I’m going to run this up the flagpole, test the waters, and see which way the wind is going to blow.
I cringe when people say “on accident.” Is it considered correct or a variant? In any case, it annoys me.
Especially since there’s already a preposition there. “Tomorrow” and “today” are actually “to morrow” and “to day.” I have some older books that even spell them “to-morrow” and “to-day.”
Amazon keeps sending me emails about books that are “on deal today.” “On deal”? Who the hell says that?
I’m currently in the mid-Atlantic region. The person I’m talking about is currently living in the same area, and is a well-educated native English speaker. I don’t know where the “on tomorrow” came from.
On Tomorrow | Britannica Dictionary suggests it’s a Southern thing. Could be that the person I’m talking about is from the South.
“organic”
“artisanal”
If I’m buying bread or coffee or cheese, then “artisanal” has significant meaning to me, because it generally reflects something about the sourcing, production, and processing of the product. Of course, the term might also be misused, as any term can be.
I hate the phrase “I’m going to Prom.” You’re going to prom what? It’s the prom! The prom! The, the, the!
“Not my first rodeo.”
“Not my circus, not my monkeys.”
Whenever I hear someone say either of these sentences, they always seem very proud of their own wit.
mmm
I know someone who does the same thing and it has been driving me crazy ever since I met her - because I don’t know one single other person who does it. This is is NYC.
After seeing a later post , I suppose it could be a Southern thing- but I know lots of people with Southern roots who don’t use this.
For me, this comes under the heading of “Cute the first time it’s heard, annoying by the tenth”.
