Etymology
It is from Latin cohortor (“to encourage, exhort”) + -tiō.[2][3][1]
Earliest recorded meaning
The TLL dates it from the Rhetorica ad Herennium,[3] which defines it as a speech that amplifies some offence and so moves the hearer to anger.[2]
Semantic evolution
In general it is an exhortation or encouragement.[2][4] The TLL counts 26 instances in Cicero and finds it very rare outside him except in the historians; the plural appears from Cicero on.[3] Cicero writes to Atticus that his exhortation moves him greatly,[4] Caesar and Nepos use it of a commander encouraging his soldiers, and Tacitus of a leader's address.[4] In Church Latin it is an exhortation.[5]
