punctilious

the word punctilious originates from the latin 'punctum', meaning 'a point' or 'a small hole', which itself derives from the verb 'pungere', 'to prick'. this literal sense evolved metaphorically in italian 'puntiglio' and spanish 'puntillo' to denote a fine point of detail or honor. entering english via french 'pointilleux', the term transformed from denoting a literal small point to characterizing a person meticulously attentive to the fine points of etiquette, procedure, or conduct. thus, the modern abstract meaning of being scrupulously precise is a direct metaphorical extension of focusing on the smallest 'points' of behavior.
