What is the meaning of Pali word "Apannaka" his question is based on the sutta translation of MN60.

What is the Pali translation of “apannaka”

https://suttacentral.net/mn60/en/sujato

Ven. Sujato translate it as “guaranteed”

Bhikkhu Bodi translate it as “incontrovertible truth”

I.B Horner translate it as “the sure”

Ven. Thanissaro translates it as “Safe Bet”

When I read the Sutta, my understanding is that the meaning is very close to the word “safe bet” even though the gambling is very un Buddhist. Perhaps I would say “safe action”
It obviously cannot be "guaranteed" because the moral realm is never guaranteed; per MN 136, MN 117, etc. Regardless of what "apaṇṇaka" means; I think a "safe bet" is the most accurate meaning, based on Dhamma principles. The idea of "incontrovertible" appears to slander the Dhamma. 

For example, moral people who hold the follow view can still suffering when their mother &amp; father die because they still believe in mother &amp; father:


  ‘There is what is given and what is offered and what is sacrificed;
  there is fruit and result of good and bad actions; there is this world
  and the other world; there is mother and father; there are beings who
  are reborn spontaneously; there are good and virtuous recluses and
  brahmins in the world who have themselves realised by direct knowledge
  and declare this world and the other world.’


MN 117, a later addition, written by an arahant, properly says the above is non-noble defiled right view siding with merit &amp; not siding with liberation. MN 117 was required to be written to straighten out other later additions, such as MN 60, which falsely say worldly right view has guaranteed results.
