Etymology
the word 'loyal' entered english in the late 15th century from the old french 'loial', 'leial', meaning 'legal, lawful, faithful'. the old french term derived from the latin 'legalis', meaning 'legal, pertaining to the law', which itself comes from 'lex, legis' (law). the semantic journey shifted from the abstract concept of 'lawful' and 'according to the law' to the more personal and moral qualities of 'faithful' and 'steadfast in allegiance'. this evolution reflects how adherence to a formal code (law) transformed into a sense of personal fidelity and devoted support.
Analysis
the word 'loyal' is a simplex loanword from french. it does not contain separable morphemes in modern english spelling.
