Forms
interesar (first-person singular present intereso, first-person singular preterite interesé, past participle interesado)[1]
Etymology
It is formed from Spanish interés + -ar.[2][1][3] The noun interés is the Latin infinitive interesse (“to be between; to concern, matter”) used as a noun;[3][4][1] The Latin verb is formed from inter- (“between”) and sum (“to be”).[3][4][1] In Spanish charters the noun appears as interesse or interese, “compensation for loss”, from 1300.[5] Terreros in 1787 gave French intéresser and Italian interessare as its equivalents.[6]
Earliest recorded meaning
Corominas dates the verb to the beginning of the 17th century, but Boyd-Bowman has it in documents of the Americas from 1529: in Mexico City someone accounts for lo que e ynteresado e gastado “what I have gained and spent”, and in Nicaragua in 1534 a man ganó e ynteresó mucho oro e plata “won and gained much gold and silver”.[3][7] Its first sense was thus “to gain, make a profit”, the sense the Diccionario de Autoridades still gave first.[8]
Semantic evolution
The Academy's dictionary of 1817 added transitive senses: to give someone a share in a business, to involve someone in another's affairs, and, in poetry, to move an audience or readers.[9] In 1843 it added “to inspire interest or affection in someone”.[10] By 1899 the moving of the audience had become the general sense “to hold the attention and feelings with what one says or writes”, and the old sense “to profit” has since dropped out.[11][2]
Today the commonest use is intransitive, me interesa “it interests me”, with the pronominal interesarse por “to take an interest in; to ask after”.[2][12] Medicine uses it for a wound or disease that affects an organ.[2][13] Corominas lists interesado and interesante among its derivatives, and dates desinteresado to 1607.[3]
