The punctuation marks in the math equation 2x(4+6) are an example of parenthesis.
- an additional word, clause, etc. placed as an explanation or comment within an already complete sentence: in writing or printing it is usually marked off by curved lines, dashes, or commas
- either or both of the curved lines, ( ), used to mark off parenthetical words, etc. or to enclose mathematical or logical symbols that are to be treated as a single term
- an episode or incident, often an irrelevant one; interlude
Origin of parenthesisLate Latin from Classical Greek from parentithenai, to put beside from para-, beside (see para-) + entithenai, to insert from en-, in + tithenai, to put, place: see do
- Either or both of the upright curved lines, ( ), used to mark off explanatory or qualifying remarks in writing or printing or enclose a sum, product, or other expression considered or treated as a collective entity in a mathematical operation.
- a. A qualifying or amplifying word, phrase, or sentence inserted within written matter in such a way as to be independent of the surrounding grammatical structure.b. A comment departing from the theme of discourse; a digression.
- An interruption of continuity; an interval: “This is one of the things I wasn't prepared for—the amount of unfilled time, the long parentheses of nothing” ( Margaret Atwood )
Origin of parenthesisLate Latin insertion of a letter or syllable in a word from Greek from parentithenai to insert para- beside ; see para- 1. en- in ; see en in Indo-European roots. tithenai to put ; see dhē- in Indo-European roots.
- A clause, phrase or word which is inserted (usually for explanation or amplification) into a passage which is already grammatically complete, and usually marked off with brackets, commas or dashes.
- Either of a pair of brackets, especially round brackets, (and) (used to enclose parenthetical material in a text).
- (rhetoric) A digression; the use of such digressions.
- (mathematics, logic) Such brackets as used to clarify expressions by grouping those terms affected by a common operator, or to enclose the components of a vector or the elements of a matrix.
Either indirectly via Middle French parenthese or directly from Late Latin parenthesis (“addition of a letter to a syllable in a word"), from Ancient Greek Ï€Î±ÏÎÎ½Î¸ÎµÏƒÎ¹Ï‚ (parenthesis), from Ï€Î±ÏÎµÎ½Ï„Î¯Î¸Î·Î¼Î¹ (parentithÄ“mi, “I put in beside, mix up"), from Ï€Î±ÏÎ¬ (para, “beside") + á¼Î½ (en, “in") + Ï„Î¯Î¸Î·Î¼Î¹ (tithÄ“mi, “put, place") (from Proto-Indo-European base *dhe- "to put, to do").
parenthesis - Computer Definition
The left parenthesis "(" and right parenthesis ")" are used to delineate one expression from another. For example, in the query list for size="34" and (color = "red" or color ="green"), parentheses group the ORs together so they are a distinct entity from the AND. In programming, parentheses are used to surround input parameters of a function call. For example, in C, the string compare statement strnicmp (itemA, itemB, 10) uses parentheses to group the ITEMA, ITEMB and 10 values handed over to the function.
