Forms

dēpositum n (genitive dēpositī); second declension[1]

Etymology

It is the neuter of dēpositus, the past participle of dēpōnō “to put down, deposit”.[2][1][3] Isidore defines it as a pledge entrusted for a time, as if ⟨diū positum⟩ “placed for long”.[4]

Earliest recorded meaning

Gaffiot's earliest citations are from Cicero, of returning a deposit.[5] Köbler dates Cicero 81–43 BC.[6]

Semantic evolution

It meant money or goods placed in another's keeping, a deposit, trust, as Cicero's reddere dēpositum “to return a deposit”.[2][5] In Quintilian it meant the contract governing a deposit, dēpositī agere to sue for breach of trust.[2]

In Ecclesiastical Latin it meant a deposit, security.[7] Medieval Latin used it for a church treasure and a temporary commission.[8] French dépôt comes from it, and English deposit came in the 1620s, first “a pledge”.[6][3]
