# If 1 Single, Two Dual, Three Triple, Four Quadruple, what are Five, 6, 7, 8, etc

The term originated as an abstraction of the sequence: single, dual, triple, quadruple, quintuple, sextuple, septuple, octuple, . *n*?tuple, . where the prefixes are taken from the **Latin** **names of the numerals**. The unique 0?tuple is called the null tuple. A 1?tuple is called a singleton, a Two?tuple is called an ordered pair and a Trio?tuple is a triple or triplet. *n* can be any nonnegative integer. For example, a complicated number can be represented as a Two?tuple, a quaternion can be represented as a Four?tuple, an octonion can be represented as an 8?tuple and a sedenion can be represented as a 16?tuple.

Albeit these uses treat *?tuple* as the suffix, the original suffix was *?ple* as in ",triple", (three-fold) or ",decuple", (ten?fold). This originates from a medieval Latin suffix *?plus* (meaning ",more",) related to Greek ??????, which substituted the classical and late antique *?plex* (meaning ",folded",), as in ",duplex",.

This question has already been answered by many others very effectively, and I very doubt that whatever I add will improve much upon that. But a man',s gotta attempt! So, here goes:

**The term originated as an abstraction of the sequence: single, dual, triple, quadruple, quintuple, sextuple, septuple, octuple.** *n***?tuple. where the prefixes are taken from theLatin names of the numerals**.

A **tuple** is a finite ordered list of elements . In mathematics , an *n***-tuple** is a sequence (or ordered list) of *n* elements, where *n* is a non-negative integer. There is only one 0-tuple, an empty sequence. An *n*-tuple is defined inductively using the construction of an ordered pair .

Single (1) (also: singleton, foot, only, etc.)

Dual (Two) (also: pair, twice)

Triple (Three) (also: triplet, treble, thrice, threesome, troika, trio)

Quintuple or Pentuple (Five)

Sextuple or Hextuple (6)

Hendecuple or Undecuple (11)

0 – empty tuple . (unit / empty sequence)

1 – single . (singleton / monuple)

Two – dual . (duo / (ordered) pair / dual / twin / product)

Trio – triple . (treble / triplet / triad)

1 million – Megadruple .

1 billion – Gigadruple .
