The word 'statutorily' is built upon the foundation of 'statute', a term for a written law formally enacted by a legislative body. This traces back to the Latin statutum, meaning "a decree or thing set up," derived from the verb statuere (to set up, establish). The adjectival suffix '-ory' (from Latin -orius) was appended to form 'statutory', meaning "relating to or enacted by a statute." Finally, the Old English adverbial suffix '-ly' was added, creating the modern adverb that describes an action performed in a manner mandated by formal law. The journey encapsulates the transformation from the concrete act of "setting up" a decree in ancient Rome to the abstract modern concept of legal compulsion.
