 | == Natural Language ==
  |  | 
 | In natural languages, number may be realised by grammatical affixes (such as "s" for plural, in English) or by quantifiers (such as "a couple of", "many", etc).<br>
  |  | 
 | In the UNLarium framework, the grammatical category of number may assume the following values:
  |  | 
 |    |  | 
 | {{#tree:id=tagset|openlevels=0|root=Number (NUM)|
  |  | 
 | *singular (SNG)
  |  | 
 | **One member of a class.
  |  | 
 | *plural (PLR)
  |  | 
 | **More than one member of a class.
  |  | 
 | **dual (DUA)
  |  | 
 | **Two members of a class.
  |  | 
 | **trial (TRI)
  |  | 
 | **Three members of a class.
  |  | 
 | **quadrual (QDR)
  |  | 
 | **Four members of a class.
  |  | 
 | **paucal (PAU)
  |  | 
 | **Few members of a class.
  |  | 
 | **multal (MUL)
  |  | 
 | **Many members of a class.
  |  | 
 | *invariant (INV)
  |  | 
 | **The word is invariant, i.e., has a single form used both in singular and plural.
  |  | 
 | }}
  |  | 
 |    |  | 
 |    |  | 
 | The number plural (PLR) subsumes more specific number values and should be used when there is no particular information on the quantity of the reference.<br>
  |  | 
 |    |  | 
 | == UNL ==
  |  | 
 | In UNL, number is to be represented by attributes, if marked. The number attribute values are the following:
  |  | 
 |    |  | 
 | {{#tree:id=number|openlevels=0|root=Number|
  |  | 
 | *@singular (default)
  |  | 
 | *@pl
  |  | 
 | **@dual
  |  | 
 | **@trial
  |  | 
 | **@quadrual
  |  | 
 | **@paucal
  |  | 
 | **@multal
  |  | 
 | }}
  |  | 
 |    |  | 
 | ;@singular is the default number value and may be omitted.
  |  | 
 | :book = book (or book.@singular)  |  | 
 | ;number, when lexicalized, should be omitted.
  |  | 
 | :glasses = glasses (and not glasses.@pl)
  |  | 
 |    |  | 
 | === Examples ===
  |  | 
 |    |  | 
 | ;@singular
  |  | 
 | :book = book or book.@singular
  |  | 
 | ;@pl (plural)
  |  | 
 | :books = book.@pl
  |  | 
 | :children = child.@pl
  |  | 
 | :livres = livre.@pl
  |  | 
 | ;@paucal (some)
  |  | 
 | :a few books = book.@paucal
  |  | 
 | :some books = book.@paucal
  |  | 
 | ;@multal (many)
  |  | 
 | :many books = book.@multal
  |  | 
 | :several books = book.@multal
  |  |
