Confidence
Probable
Formation
Derivation
First attested
c. 1230
Ultimate origin
Latin cōnsuētūdō

Forms

custumārius (feminine custumāria, neuter custumārium); first/second-declension adjective[1] Also spelled customārius, costumārius and custimārius.[1][2]

Etymology

It is from Latin custuma + -ārius,[1] from the Medieval Latin word for custom and customary payment, which the DMLBS derives from Old French custume, from cōnsuētūdō (“custom”).[2] Etymonline instead calls it a contraction of cōnsuētūdinārius.[3]

Earliest recorded meaning

Köbler cites Latham for the noun about 1230.[1] The DMLBS's earliest dated quotation is from a forest inquest of 1244, which asks whether foresters have custumarii paying them yearly rents.[2]

Semantic evolution

The word belongs to the records of English manors, towns and ports.[2] As an adjective it described land, services and payments owed by custom, and a person bound by custom; as a noun it was the customary (unfree) tenant.[2][1] It also named a customer owing suit at a lord's mill, a toll-paying member of a guild, and a collector of customs in England and Scotland, while the neuter meant a custumal, a book of customs.[2] An adjective “habitual” was used of offenders and of merchant ships that called regularly.[2]

Through Anglo-French custumer it gave English customer, first a customs official and then a regular buyer, and later customary.[3] The customs collector is still the sense in Camden's annals of 1590.[4]
