Forms

désintéresser[1]

Etymology

It is formed from French dés- + intéresser.[2][3][4][1][5] Rey notes that it reflects both main values of the base verb, the financial one (“to give a share in a profit”) and the psychological one (“to arouse interest”).[6]

Earliest recorded meaning

The TLFi's first record is in Robert Estienne's Latin–French dictionary of 1552, which renders Latin praestare aliquem indemnem as le desdommager et rendre indemne, le désintéresser: to indemnify someone.[2] The Grand Robert and the GLLF date the word to the same year but credit it to Rabelais.[3][4]

Semantic evolution

The first sense was financial and legal: to put someone out of an affair by paying them what they were owed, as in désintéresser ses créanciers.[2][6][7] The pronominal se désintéresser de “to stop taking an interest in” is recorded from the end of the 17th century and became the commonest use;[6][4][7] classical French also had se désintéresser sur, “to pay no heed to”, used by La Bruyère.[4]

The past participle désintéressé was first used of someone indifferent, then from 1665 of someone who acts without regard to personal, especially financial, gain;[6] the TLFi finds it in Pascal's Pensées before 1662.[2]
