Etymology

It is the neuter of compositus, the participle of compōnō “to put together”, used as a noun.[2][1] ⟨compōnō⟩ is from con- and pōnō (“to put”); de Vaan explains ⟨pōnō⟩ from ⟨*po-sinō⟩ “to put down”.[1][3]

Earliest recorded meaning

The OLD's earliest citations are from Sallust, ex compositō “by arrangement”, and of law and order.[2] Köbler dates Sallust 86–34 BC.[4]

Semantic evolution

In the phrases ex compositō and dē compositō it meant by prearrangement, in concert, as in Sallust and Livy; in the plural, a settled or peaceful situation, law and order, as in Sallust; and in Pliny a compounded medicine.[2]
