This is the valency-decreasing meaning on monovalent stems. The result is an avalent stem, which can only take an impersonal 3sg or 4sg ending.

• ingittariaqarpoq, one (people) ought to sit down [CWSL58]
  

  From ingippoq, 'he sits down'. This is difficult to translate directly, since the meaning is avalent; i.e. something like 'there ought to be down-sitting', without directly saying who it is that ought to sit down.

• anisariaqarpoq, one (people) must go out [SK71]
  

  From anivoq, 'he goes out/exits'.

• anniariaqarpoq, one must suffer (i.e. tolerate) the pain [SK71]
  

  From anniarpoq, 'he suffers/feels pain'.

This is the valency-decreasing meaning on divalent stems. The result is a monovalent stem with the Patient promoted to Actor. The Agent can optionally be specified in the allative case.

• kaattariaqarpoq, it must be hammered [CWSL58]
  

  Or 'there must be hammering', from kaappaa, 'he strikes it' (with a stone or hammer).

• salittariaqarpoq, it must be cleaned [CWSL58]
  

  From salippaa, 'he cleans it'.

• ornittariaqarpunga, I must be approached [CWSL58]
  

  From ornippaa, 'he approaches him'. This example is difficult to translate directly. The meaning is something like: 'they must come to me', but without mentioning who 'they' are; i.e. 'I must be come-to'ed'.

• nersortariaqarputit, thou ought to be praised [CWSL58]
  

  From nersorpaa, 'he praises him'.

• uannut ataqqisariaqarpoq, he ought to be honoured by me [CWSL58]
  

  From ataqqivaa, 'he honours him'. Note that the underlying Agent 'I' is here added in the allative case (uannut).

• paarisariaqartippara, I consider it necessary that it is looked after [CWSL58]
  

  From paaraa, 'he looks after it'. Here the stem is first passivised, i.e. paarisariaqarpoq, 'it must be looked after', and then transitivised with V{tət}V in the sense of 'think/consider'.

• atortariaqarpoq, it must be used [CBBJRPIKJR97]
  

  From atorpaa, 'he uses it'.

This is the newer, valency-preserving meaning, which Kleinschmidt [SK71] considered incorrect, but is common today. It can be used on stems on any valency and does not affect the roles.

• makittariaqarpoq, he has to get up [CBBJRPIKJR97]
  
• sinittariaqarpoq, he needs to sleep [CBBJRPIKJR97]
  
• qimaasariaqarpoq, he must flee [CBBJRPIKJR97]

• utoqqatsertariaqarputit, you ought to apologize
  
• pujortartariaqanngikkaluarpunga, I ought not to smoke (but ...)
  

  With V{ŋŋit}V (negation) and V{galuaq}V (but ...).

• pisariaqarpoq, it is necessary [CWSL58]
  

  With the dummy root {pi}V, giving the pure meaning of the affix.

• tigusariaqarpara, I must take it [CWSL58]
  

  From tiguaa, 'he takes it'.

• taama taasariaqanngilaa, he ought not to call him thus [CWSL58]
  

  From taavaa, 'he names/calls him (something)', and with the negation affix V{ŋŋit}V.

• eqqaamaneqatariaqarpoq, it must be remembered [FAJN19]
  

  From eqqaamaneqarpoq, 'it is remembered'. Here, the passivising affix V{nəqaq}V has been added in front of the present affix to clarify that the passive meaning is intended.
