This questions is probably strange, but I will give an example. The concept of money, for example is understood by almost all languages, or take the concept of mathematics. Is there an actual word for this?
Meaning a word or concept that is understood across all cultures.
Omni means 'all, of all things'
Cultural means 'relating to the ideas, customs and social behaviour of a society'.
Money is an omni-cultural concept, understood globally
the United Nations creates omni-cultural programmes for global education, peace and wellbeing
'why omni-culturalism not multi-culturalism is the solution'
