adat
UK[ˈɑːdɑːt]US[ˈɑːdɑːt]
n
The customary law, traditions, and social codes of conduct of a particular community or ethnic group, especially in Indonesia, Malaysia, and other parts of Southeast Asia.
Etymology
The word 'adat' entered English as a direct borrowing from Malay and Indonesian, where it refers to customary law and tradition. Its ultimate origin is from the Arabic word 'ʿādah' (عادة), meaning 'custom', 'habit', or 'practice', which itself is derived from the root 'ʿ-w-d' relating to returning or repeating. This etymological journey—from an Arabic concept of habitual practice to a specific term for the complex, traditional legal systems of Southeast Asian communities—illustrates the transmission of cultural and legal concepts through language contact. In English, it functions as a precise anthropological and legal term to describe these indigenous systems distinct from Western or religious law.
Analysis
This word is a direct loanword from Malay/Indonesian. It is not productively formed from smaller morphemes within the English language.
