IPA: /ˈpækʧən/
KK: /ˈpækʧən/
A formal agreement or treaty between two or more parties.
The two countries signed a paction to promote peace and cooperation.
Paction is derived from the Latin 'pactio' (meaning agreement or compact), which comes from 'pactum' (meaning something agreed upon). The suffix '-ion' indicates the action or process. Thus, 'paction' refers to the act of making an agreement or compact.
Think of 'pactum' as an agreement, and remember that 'paction' is the action of making that agreement.
