Hi, ![Smile [:)]](/emoticons/emotion-1.gif)
speaking about North American English, what are the terms that are usually used along with parenthesis or parentheses? I'll give you some examples so you'll be able to better understand what I mean:
- Usual name of ( and ). ( Is it open/close parenthesis? I wonder why close and not closed...)
Maybe because these could be instructions to the person writing. (See example below.)
- What to say when you want somebody to write a parentheses, for example while you are dictating something.
- Is it possible to use the verb to open and to close with parenthesis? Example: "You forgot to close the last parenthesis" or "The teacher said to open a parenthesis before the word 'example'".
Yes. "Put a left parenthesis before 'example'". (Sometimes people say 'paren' for short, but not everyone does this.)
Is "to open a parenthesis" an idiomatic expression? (like "I'd like to open a parenthesis about this issue...") Not that I know of.

Example
If I'm telling someone to write
(2x2 + 3y) - 17
I’d say:
parenthesis (or open parenthesis/es, or left parenthesis)
2 x squared
plus 3 y
close parenthesis (or right parenthesis)
minus 17
