"Mundification" Natural Recordings by Native Speakers
Mundification is not a commonly used word in English. However, based on itsROOTmundus, which means "world", I would interpret "mundification" as a process of giving a sense of reality or making something more worldly or tangible. It could also imply a reference to the physical or material world, making something more concrete or real.
Munera is a Latin word that refers to a gift or a tribute given to a Roman general upon his return from a successful campaign. As an adjective, munerary means "relating to or given as a gift or tribute, especially in the form of money or spoils of war".
