To clearly mark the facilities, buildings, places for the public or visitors, we usually put a signboard on each of them. Does it need to capitalize the first letter of the word on the signboard? For examples as below.
1. “playground" or “Playground”
2. “swimming pool” or “Swimming Pool”
3. “gymnasium” or “Gymnasium”?
4. “library” or “Library”
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
Conversely — perhaps perversely — lower case letters are increasingly used deliberately for 'stylistic' reasons where capitals are normally mandatory.
I still grit my teeth when I see signs like 'liverpool echo arena' and 'the sir percy verance conference centre'.
Students of the language should be aware of this when they see such examples but be assured that it is not considered to be standard practice.
