Etymology

Used as a noun, it is the neuter past participle from Latin cōgitō (“to think, consider”).[1][3][4]

Earliest recorded meaning

The OLD's first example is in Terence's Phormio, of someone who could not bring out what he had thought out (nōn potuit cōgitāta prōloquī).[1] Köbler dates it from Nepos.[5]

Semantic evolution

It is mostly used in the plural.[4][2] Cicero praises speakers who could express their thoughts brilliantly,[1][4] and also uses it of a plan or design, as of carrying out a plot.[1][3] Nepos uses it of a general's scheme and of revealing someone's plans,[1][3] and Frontinus of keeping plans hidden.[1] Quintilian uses it of what a speaker has thought out beforehand.[1] In Ecclesiastical Latin it means a thought, reflection or idea.[6]
