interrogator

The word 'interrogator' has a direct lineage from Latin. It is built upon the verb interrogāre, meaning "to ask questions, to examine," which itself is a compound of the intensive prefix inter- and the verb rogāre, "to ask." The agent noun suffix -ātor was then appended to form interrogātor, literally "one who asks questions intensively." This Latin term passed into English in the 15th century, preserving its core meaning of a formal questioner. The modern sense, often implying a systematic or forceful examination, retains the logical essence of its ancient components: intensive (inter-) asking (rog) by an agent (ator).

Structure: inter + rog + ator - inter: Latin origin, meaning "between, among". In this word, it functions as an intensifying prefix. - rog: Latin origin, from the root rogāre, meaning "to ask, to question". It is the core lexical root. - ator: Latin origin, a suffix (-ātor) forming agent nouns, meaning "a person or thing that performs the action of the verb". It functions as a noun-forming suffix.
