Pronunciation
- (UK) IPA(key): /?t?p?l/, /?t??u?p?l/, /?tju?p?l/
- (US) IPA(key): /?tu?p?l/, /?t?p?l/
- Rhymes: -u?p?l, -?p?l
Noun
tuple (plural tuples)
- (set theory) A finite sequence of terms.
- A tuple is not merely a totally-ordered set because the same element can appear more than once in a tuple: for example, qualifies as a 3-tuple whereas it would not qualify as a totally-ordered set (of cardinality 3), because the set would be where and so that ; i.e., it would actually be a one-element set, , not even just two-element.
- If commutativity were added to a tuple, it would turn into a multiset or "bag". For example, words (of some alphabetic language) can be considered to be tuples of letters. If the ordering requirement on those letters were lifted, then the word would become a multiset of letters equivalent to those of its anagrams.
- (computing) A single row in a relational database.
- (computing) A set of comma-separated values passed to a program or operating system as a parameter to a function call.
- (computing) In some programming languages, a data type that is similar to but distinct from the list data type, whose instances are characterized by having a rather fixed arity, and the elements of which instances can differ from each other by data type. (Note: this definition may overlap with the previous one.)
- Both Python and Haskell have a tuple data type as well as a list data type.
- Unlike lists, tuples are not formed by consing.
Synonyms
- (finite sequence of terms): n-tuple (when the sequence contains n terms), ordered pair (when the sequence contains exactly two terms), triple or triplet (when the sequence contains exactly three terms)

- (set theory) A set of ordered tuples.
- […] Signs are, first of all, physical things: for example, chalk marks on a blackboard, pencil or ink marks on paper, sound waves produced in a human throat. According to Reichenbach, "What makes them signs is the intermediary position they occupy between an object and a sign user, i.e., a person." For a sign to be a sign, or to function as such, it is necessary that the person take account of the object it designates. Thus, anything in nature may or may not be a sign, depending on a person's attitude toward it. A physical thing is a sign when it appears as a substitute for, or representation of, the object for which it stands with respect to the sign user. The three-place relation between sign, object, and sign user is called the sign relation or relation of denotation.
