interrogatory

The word 'interrogatory' is built upon the Latin verb interrogare, which itself is a compound of inter- ("between") and rogare ("to ask"). The core logic is of asking questions between parties, implying a formal exchange or dialogue of inquiry. The suffix -ory was added to form an adjective in Latin, later adopted into English to describe something pertaining to questioning. Over time, while the adjective retains the general sense of being questioning, the noun form became specialized in English common law to denote a formal list of written questions posed by one party to another during pre-trial discovery, thus preserving the ancient sense of a structured, inter-party inquiry.

Structure: inter + rog + atory - inter (Latin origin): A prefix meaning "between, among". - rog (Latin origin): A root from the verb rogare, meaning "to ask, to propose a law". - atory (Latin origin): An adjectival suffix meaning "relating to, characterized by".
