Etymology
It is inherited from Latin prīmus (“first”), which figuratively came to mean “of the first quality”.[2][3][4] In the sense “cousin” it is a shortening of cōnsobrīnus prīmus (“first cousin”), literally “first cousin” as against the second and third cousins, to whom the word was later extended.[2][3][5] Latin cōnsobrīnus alone meant rather a second cousin or a more distant relative, so the longer phrase was needed and was later worn down.[2][6] Castilian kept the Latin word for cousin itself as sobrino “nephew”.[7][3]
In the proper sense “first” Spanish replaced the Latin word with primero from the start;[2] the Spanish word in that sense, from the Glosas Silenses to Juan Ruiz, is a Latinism.[2] Wiktionary accordingly treats the adjective “first, prime” as a borrowing from Latin.[1]
The Latin adjective goes back to Proto-Italic *prīzmos, a superlative of an obsolete preposition *pri (“before”); de Vaan builds it on an adverb of that form with the superlative suffix *-isamo-, and calls the PIE ancestry of this adverb uncertain.[1][8]
The cousin sense is an innovation of Portuguese primo and Spanish.[2] Elsewhere the Latin adjective gave Catalan prim (“thin, fine”), Occitan prim and Italian primo, while French cousin, Catalan cosí and Italian cugino continue the Latin word for cousin.[7][2] Corominas rejects the usual explanation of the French type as a nursery shortening and derives it from a contraction of the Latin phrase, as in southern Italian dialects.[2]
Earliest recorded meaning
Both main senses are in the Cantar de mio Cid (c. 1140): un brial primo de ciclaton, “a fine tunic of silk”, and primo eres de mis fijas, “you are my daughters' cousin”.[9][2][3] The cousin sense also appears in a charter of 1194.[2]
Semantic evolution
The old adjective meant “excellent, fine”, and also “scrupulous, subtle”;[2] Aragonese used it for fine as opposed to coarse cloth (tela prima, 1373 and 1497), the sense that became Catalan prim “thin”.[2] Covarrubias in 1611 called a shoemaker de obra prima one who makes fine shoes.[10] The Diccionario de Autoridades (1737) gives primo as “first”, as “excellent, skilful”, and as the son of an uncle, with primo hermano, segundo, tercero.[11]
In 1884 the Academy added the title the king gave to the grandees of Spain and the colloquial sense of a simple, gullible person.[12] Corominas takes the latter from the old sense “subtle, refined”, used ironically: in Cuba primo meant a simple rustic (le cogí de primo). The colloquial “the one who pays for others, the dupe” comes from this Cuban use.[2][3] Wagner preferred a figurative use of the kinship word, the country cousin whom everyone exploits.[2][3] Número primo is the mathematician's prime number.[13][1] In Spain primo is also a slang form of address among young men, and in several countries of Central and South America it means simply a man or woman, or a close friend.[1][14]
