IPA: //ˈdɛkəˌlɒɡ//
KK: /ˈdɛkəˌlɔg/
A set of ten principles or rules, often referring to the Ten Commandments in the Bible.
The Decalogue serves as a moral foundation for many religious traditions.
Decalog is formed from "deca-" (from Greek "deka", meaning ten) and "logos" (from Greek "logos", meaning word or discourse). The term refers to the Ten Commandments, which are ten words or principles.
Think of 'deca-' meaning ten and 'logos' meaning word — that's why a decalog refers to a set of ten words or commandments.
