dictiōnārius m (genitive dictiōnāriī); second declension[1]
Etymology
It is from Latin dictiō (“saying; speech”) + -ārius,[1] short for ⟨dictionarius liber⟩, a “book of words”.[2][3] The first part is a noun of action from dīcō2 (“to say”).[4][3]
Earliest recorded meaning
Its earliest record is John of Garland's Dictionarius,[3] before 1250,[5] which explains its title: the little book is called dictionarius from the most necessary words (dictiones) that every scholar should keep not only in a wooden chest but in the cupboard of his heart.[2]
Semantic evolution
Later medieval book inventories list copies of a dictionarius, also spelled dixionarius,[2][5] and Polish and Bohemian sources use it for a dictionary or lexicon.[6][7] Renaissance humanists such as Decembrio, Thomas More and Erasmus still used the masculine, and by metonymy it could also mean the compiler of a dictionary.[8][2] A rare adjective, “of a dictionary”, appears in Sixtus of Siena.[8]
The neuter dictionarium became the commoner form, and it is the source of English dictionary.[3][1]
