Pronunciation

Forms

isolé (feminine isolée, masculine plural isolés, feminine plural isolées)[1]

Etymology

It is borrowed from Italian isolato (“built as an islet, separated”), the past participle of isolare (“to make like an island, to separate”), from isola (“island, block of houses”), which comes from Latin insula, the source also of île.[2][3][4][5][1] Bloch and Wartburg note that the Italian verb seems to be later than the adjective, as the French verb is.[6]

Earliest recorded meaning

It is first found in 1575, in Guillaume Paradin, in the sense “shaped like an island”.[2][5] It began as a term of architecture, for what forms a free-standing building, and spread in the second half of the 17th century (Félibien, 1676, of a column or a house).[3][4][6]

Semantic evolution

It was applied to a person cut off from others in 1694 (Boursault, cœurs isolés) and in La Bruyère (1696).[2][3] In the 18th century it was used of a passage detached from its context (Rousseau, 1758) and of a place standing apart (Voltaire, Candide, 1759).[2][3]

Condorcet used it of facts separated from their surroundings for analysis (1794), and Lamennais of a fact that is rare or unique (1831).[2][3] In military use it named a soldier belonging to no unit (1835), also as a noun (1893), and in electricity a body not in contact with a conductor (1867).[3][5] The verb isoler, formed from the adjective, followed in 1653.[6][3]
