Forms
interés m (plural intereses)[1] Medieval texts write interesse, interese and enteresse; the form interesse was still common in the 16th century and appears in the first part of the Quijote.[2][3] Ladino has entereso.[4]
Etymology
It is borrowed from Medieval Latin interesse (“compensation; interest on a loan”), the infinitive of the Latin verb “to be between; to matter” used as a noun.[5][6][2] The Medieval Latin noun meant damages for a broken contract and the interest on capital.[7][8] The DLE glosses the Latin verb as “to matter”.[9]
The same Medieval Latin noun gave Portuguese interesse, Italian interesse and French intérêt; the French word, recorded in 1290, comes rather from the Latin third person interest (“it matters”).[10][11][12]
The verb is formed from Latin inter- (“between”) + sum (“to be”).[13][2]
Earliest recorded meaning
The early hits of the CDH are the Latin verb in Latin charters.[14] The first in a Castilian text is a lease of 1300, where it is the compensation owed for late payment: que diese por razón de dannos e de interesse al cabildo “that he should give the chapter, by way of damages and interest”.[14] The DEMel cites the spelling jnterese in the legal treatise of Maestre Jacobo (1252–1289).[3]
Semantic evolution
In the 14th century the word belonged to the language of contracts, where it appears again and again in the formula por nombre de pena e de interesse e de postura, the penalty and compensation agreed for a broken undertaking.[14] Terreros separates the sense of whatever concerns one's estate, love or comfort from the money earned by capital.[15]
The Academy's 1843 dictionary lists profit, value, a strong inclination of the mind towards a person, object or story, the earnings of money, and in the plural one's fortune.[16] The modern dictionary keeps these senses, and adds the plural for one's moral or material advantage.[9] Set phrases of finance and law include interés compuesto “compound interest” and interés legal “legal interest”.[9][1] In the Americas the word appears from 1520, in Cuba.[17]
