orator

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).

orator (n.)

late 14c., "one who pleads or argues for a cause," from Anglo-French oratour (Modern French orateur), from Latin orator "speaker," from orare "to speak, speak before a court or assembly, pray, plead," from PIE root *or- "to pronounce a ritual formula" (cognates: Sanskrit aryanti "they praise," Homeric Greek are, Attic ara "prayer," Hittite ariya- "to ask the oracle," aruwai- "to revere, worship"). Meaning "public speaker" is attested from early 15c.
