If you think that parentheses are spelt with a "d", you're certainly
confused :-)
They're all brackets. Often the type of bracket doesn't matter, but when
it does, adjectives do a perfectly fine job at distinguishing one from
the other: round brackets, square brackets, and curly brackets are
well-known and in common use all over the Commonwealth, and have been
established since the mid 1700s.
As a sop to Americans, who I understand are easily confused by ordinary
English *wink*, the Unicode consortium describes () as parentheses:
py> unicodedata.name("(")
'LEFT PARENTHESIS'
but [] and {} are described as brackets:
py> unicodedata.name("[")
'LEFT SQUARE BRACKET'
py> unicodedata.name("{")
'LEFT CURLY BRACKET'
As are angle brackets:
py> unicodedata.lookup("LEFT ANGLE BRACKET")
'〈'
py> unicodedata.lookup("RIGHT ANGLE BRACKET")
'〉'
HTML uses ASCII less-than and greater-than signs as angle brackets.
Physicists even have a pun about them, with "bra-ket" notation for
quantum state:

There are a number of other types of brackets with more specialised
uses, or common in Asian texts. See http://en.wikipedia.org/wiki/Bracket
By the way, the word "bracket" itself is derived from the French and
Spanish words for "codpiece". That's not relevant to anything, I just
thought I'd mention it.
