What's the name for a group of letters that create a unified information/message? (I'm looking for a general name whether they are on a sign, engraved, or written.)
If I write myself a note on a paper, is it a sign?
If a building has a name of the enterprise on it, can I say it's written on it whatever is the format of the letters?
If the name of the enterprise is engraved or embossed, what to call it? Can I call it sign?
In Czech, I'd call all of these nápis, which translates as sign, inscription, lettering but I'm confused about differences between them.
