Etymology and origin of the English word -ory
Dictionaries separate a noun suffix -ory and an adjective suffix -ory, though the Latin sources are closely related: the noun comes from forms of the adjective.[1][2][3][4]

Etymology
The noun suffix is inherited from Middle English -orie,[2][6][4] borrowed from Anglo-Norman -orie and Old French -orie, beside usual Old French -oire,[1][6][7][8][3] from Latin -ōria, as in glory and victory, but often answering to -ōrium,[1][3][8] the neuter of the adjective suffix -ōrius.[2][3][4][7]
Earliest recorded meaning
In Latin the neuter adjective early became a noun for the residence of an agent or the instrument used, according to an etymological dictionary of French quoted by Etymonline, as in dormitōrium and auditōrium.[7] Such words became very numerous in church and academic Latin, as with purgātōrium and refectōrium.[7] The earliest English examples are from Middle English, with purgatory in the 13th century.[1]
Semantic evolution
Following those early borrowings from Anglo-Norman, -ory became the normal English form of -ōrium and -oire.[1][6] Borrowings were numerous until about 1700, but most are now rare or obsolete, and few have appeared since.[1] English formations, chiefly on Latin past participle stems or the verbs derived from them, begin around 1500, with masticatory and later observatory.[1] Some have more common doublets that keep the Latin form, such as auditorium and crematorium beside auditory and crematory.[1] Other words were assimilated to the ending in the 15th and 16th centuries, as fumitory and pellitory were.[1] In priory and rectory it is instead a noun in -or with -y.[3]

Etymology
The adjective suffix is inherited from Middle English -orie,[2][6][4] borrowed from Anglo-Norman -orie, beside Old French -oire, and directly borrowed from Latin -ōrius,[1][2][10][8][3] made up of the agent suffix -or, the source of -or2, and the adjective suffix -ius.[1][6][4][3]
Earliest recorded meaning
Latin formed these adjectives chiefly from agent nouns in -tor and -sor, as in accūsātōrius and suāsōrius.[1][6] According to the same French dictionary, quoted by Etymonline, they marked a quality proper to what the agent does.[7] Loanwords appear in English from the Middle English period on, starting with accusatory in the 14th century.[1]
Semantic evolution
Loans went on to about 1700 and peaked in the 17th century, and few came after.[1] Formations on Latin past participle stems date from the 15th century, as with contributory.[1] English also formed words on its own verbs of Latin origin, especially those in -ate, and here the suffix remains productive, as with advisory, statutory and supervisory.[1][3] Parallel forms in -ive are often the commoner choice, as with punitory and punitive, though derisory and derisive differ.[1] Often English uses the extended -orial or, less often, -orious instead.[1][3]
Timeline
- 14th century – accusatory.[1]
- 15th century – peremptory, and the first English formations, such as contributory.[1]
- 16th century – desultory.[1]
- 17th century – contradictory; loans at their peak.[1]
- 18th century – advisory, statutory.[1]
- 20th century – celebratory.[1]
