The category of indefinite pronouns borders on the indefinite adverbials such as earne somewhere, nearne nowhere, ea ever and nea never on the one hand and the indefinite numerals such as guon some or ider(e) each, any, every on the other. Grammars differ in what is included in the term indefinite pronoun. However, there is not much disagreement about the following set:

Some individual indefinite pronouns will be Commonted on below, with the exception of men one.

• When al(le) all is used attributively, it is counted as a quantifier (see (a)), but when it is used otherwise, it is conceived of as an indefinite pronoun (see (b)):
  Example 3

  
  

  a.	Hy komt alle dagen
  	he comes all days
  	He comes every day

  b.	Al wat er die, mislearre
  	all what he did failed
  	Everything he did failed

• Eat something mainly occurs in written language, in spoken language wat something is used. Wat something does not neccesarily refer to an earlier-mentioned referent (see sentence (5a)), but it may also be used anaphorically (see (5b)) (see Hoekstra (1987)):
  Example 4

  
  

  a.	Sjoch, der leit wat yn 'e sleat
  	see, there lays something in the ditch
  	Look, there is something in the ditch

  b.	Wolst ek noch kofje? Ja, jou my noch mar wat
  	will.you also still coffee? yes, give me still but something
  	Do you want to have a cup of coffee? Yes please

  However, in the latter case wat could be better considered an indefinite quantifier.

  Instead of eat and wat, the wordgroup in ding a thing something can also be used (see Hoekstra (1989)):

  Example 5

  
  

  Dat is in ding dat tige ús omtinken fertsjinnet

  that is a thing that very our attention deserves

  That is something that seriously deserves our attention

  In ding can also be combined with an adjective, for example goed good:
  Example 6

  
  

  It soe in goed ding wêze

  it would a good thing be

  That would be a good thing

• The forms elts, eltsenien each are variations of the forms elk, elkenien each, as a result of historical palatalization of /k/. For more details about these forms, see Hoekstra (1987) and quantifiers. There is also the distributive form elkmes, as in
  Example 7

  
  

  Se krigen elkmes in priis

  they got each a price

  Each of them got a prize

• Guon some has a large number of additional (sometimes dialectical) variants. A few examples of them are: guont, guons, guonts, guonnen, guonnent (Hoekstra (1987)). In Frisian, one may use guon without any introduction in sentences like the one in (8); it can only be interpreted then as more than one person:
  Example 8

  
  

  Op in jûn hearde er guon by de doar

  at a night heard he some at the door

  At one night, he heard some people at the door

  In Dutch, however, this is impossible with the counterpart sommige:
  Example 9

  
  

  *Op een avond hoorde hij sommigen bij de deur

  at a night heard he some at the door

  At one night, he heard some people at the door

  The Dutch equivalents sommige(n), enkele(n), enige(n) have to refer to an earlier mentioned referent:

  Example 10

  
  

  Van de mensen uit het koor, hoorde hij op een avond sommigen bij de deur

  of the people from the choir, heard he on a night some at the door

  Of the people from the choir, he heard some of them at the door one night

• The phrase ien of oar one or the other is used as a prenominal modifier indicating the indefiniteness of the Noun Phrase (NP) (De Haan (2001:178)): de ien of oare gek some crazy person, it ien of oare ferhaal some story. The article de / it the / it in these phrases does not convey definiteness; its gender is determined by the nominal head.
• Immen somebody and its negative counterpart nimmen nobody are mainly restricted to written language. They are replaced by ien and negative gjinien or net ien.
• Neat nothing has a stronger position in spoken language than eat, but is nevertheless often replaced by Dutch niks nothing.
• The use of wa who as an indefinite pronoun is not so frequent; it is only used in sentences like (11):
  Example 11

  
  

  Is der wa?

  is there who

  Is there someone?

  Der wie wa by de doar

  there was who at the door

  There was someone at the door
  It occurs attributively in exclamative sentences like
  Example 12

  
  

  Wa minske docht soks!

  who human.being does such.a.thing

  Who on earth does something like that!

  Instead of wa, one mostly encounters the much more common indefinite pronoun ien.
• Some pronouns have genitive forms. A restriction is that they should refer to people:
  Example 13

  
  

  a.

  elks belang

  everybody's interest

  b.

  elkeniens flater

  everybody's fault

  c.

  immens bern

  someone's children

  d.

  nimmens skuld

  nobody's fault

Indefinite adverbials, which are sometimes included among the indefinite pronouns, refer to places: earne somewhere, nearne nowhere, or time: ea ever, nea never:
