“ A legal doublet is a standardized phrase used frequently in English legal language consisting of two or more words that are near synonyms, usually connected by "and", and in standard orders, such as "cease and desist".
The doubling—and sometimes even tripling—often originates in the transition from use of one language for legal purposes to another… To ensure understanding, the terms from both languages were used. This reflected the interactions between Germanic and Roman law following the decline of the Roman Empire.”
