In English,

I go to the store.

is understood to mean

It is true that I go to the store.

Suppose I want to succinctly express

  1. I am indifferent to whether it is true or false that I go to the store.


  1. I do not know whether it is true or false that I go to the store.

How would one say this in English? Are there other languages whose verbs are truth-neutral or truth-indifferent instead of truth-committed as in English?

cf. this English Language Learners StackExchange question: "Help pinpoint the usage of 'could' in these examples."

    That is called evidentiality.

    @YellowSky Evidentiality requires a source of information, which neither of the examples seem to contain. I think these are cases of modality. May 12, 2018 at 16:23
  • This is called modality (which subsumes evidentiality). Verbs in natural languages typically default to so-called positive modalities, other modalities need always be expressed periphrastically.
