I was going to spend a few hours collecting different forms/names for numbers depending on their function and make a Numbers spreadsheet out of it, but I decided it might be more fun to start a thread and "crowdsource" the task.

Let's see who can find the most "obscure" forms... but don't be afraid to post common, everyday forms, either.

I'm listing the forms I collected side-by-side to save vertical space, but I'll be happy to create a decent spreadsheet when more data is collected and share it as a .Numbers file with any interested folks.

Arabic numerals // Set of x works of art that are connected, and that can be seen either as a single work or as x individual works // ordinal numbers for precedence/effect // musical ensemble comprised of x members

Code:
1        monology                 primary              solo
2        duology                  secondary             duet
3        trilogy                  tertiary              trio
4        tetralogy                quaternary            quartet
5        pentalogy                quinary               quintet
6        hexalogy                 senary                sextet
7        heptalogy                septenary             septet
8        octalogy                 octonary              octet
9        ennealogy                novenary              nonet
10       decalogy                 decenary              dectet
11       endecalogy               undenary              ?
12       dodecalogy               duodenary             ?
Interesting tidbit:

From oxforddictionaries.com:

What comes after once, twice, thrice?

Nothing! These three are the only words of their type, and no further terms in the series have ever existed.

UPDATE: Please ignore the word "code" above. Its only purpose is to keep the spacing (and columns) from getting messed up after posting.

Here's my second contribution to this thread.

Polygons:

Code:
Edges    Name           Remarks
1        henagon        Not generally recognized as a polygon*
2        digon          Not generally recognized as a polygon in the Euclidean plane**
3        triangle       The simplest polygon which can exist in the Euclidean plane.
4        quadrilateral  The simplest polygon which can cross itself.
5        pentagon       The simplest polygon which can exist as a regular star
6        hexagon        Alternative "sexagon" = Latin [sex-] + Greek.
7        heptagon       Alternative "septagon" = Latin [sept-] + Greek.
8        octagon
9        enneagon
10       decagon
11       hendecagon     Alternative "undecagon" = Latin [un-] + Greek.
12       dodecagon      Alternative "duodecagon" = Latin [duo-] + Greek.

* Some disciplines such as graph theory use the term.
** It can, however, exist as a spherical polygon.
Bonus: what do you call a polygon with an infinite number of edges?

An apeirogon.

  • Degree 0 – constant
  • Degree 1 – linear
  • Degree 2 – quadratic
  • Degree 3 – cubic
  • Degree 4 – quartic
  • Degree 5 – quintic
  • Degree 6 – sextic (or, less commonly, hexic)
  • Degree 7 – septic (or, less commonly, heptic)


For higher degrees, names have sometimes been proposed, but they are rarely used:
