orator [orator 词源字典]: orator: [14] Orator is one of a small family of English words that go back to the Latin verb ōrāre ‘speak’. Others include oracle [14], oration [14] (whence, by back-formation, orate [16]), and oratory ‘public speaking’ [16]. And besides these, there is a special subset of words that depend on a later, extended sense of ōrāre, ‘pray’: adore [15] (etymologically ‘pray to’), inexorable, oratory ‘small chapel’ [14] (whose Italian form has given English oratorio [18]), and the now archaic orison ‘prayer’ [12] (etymologically the same word as oration).
