Etymology

It is inherited from Latin post (“after; behind”).[2][3][4] Wiktionary gives a reduced form Vulgar Latin *pos as the intermediate stage.[1] In late Latin the word also took the value of postquam (“after; since”), and Corominas, following Löfstedt, thinks the conjunction comes from this use rather than from the adverb “afterwards”.[2][3] The adverb survived in Old Spanish in the sense “afterwards”, in the Vida de Santa María Egipcíaca, Berceo and the Libro de Alexandre.[2]

The same Latin word is Portuguese pois, Galician pois, Asturian pos, French puis, Italian poi and Romanian apoi.[5][6][1] Old Portuguese pós was almost only a temporal preposition.[2] Cunha derives the Portuguese word from a variant *posti, since the classical form does not explain its ⟨i⟩.[7] después is a compound, an alteration of Old Spanish depués, from Vulgar Latin de post.[3][5]

The Latin word comes from poste, *posti and *pósti.[1][8] The worn-down colloquial forms ⟨pus⟩ and ⟨pos⟩ are recorded from the 16th century, ⟨pus⟩ in the Farsa of Alonso de Salaya.[2]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, in a 14th-century copy) already uses pues as a causal and an illative conjunction: „Pues adelant irán tras nós, aquí sea la batalla” “since they will come on after us, let the battle be here”.[9][2] Menéndez Pidal also lists a temporal use, “after”.[10]

Semantic evolution

The causal and illative senses have been constant in every period.[2] In classical writers pues often introduced a short causal clause where today one would say puesto que, and it could be emphatic, as in Tirso's „Tú, pues”.[2] Autoridades (1726–1739) described it as a particle of resolution or inference, usually placed after the first word of the clause, and equivalent to supuesto que.[11]

In the Spanish of the Basque Country pues is used at the end of almost any phrase, perhaps on a Basque model; in Chile it is reduced to pu or po as an emphatic particle, and in Argentina it appears in replies such as sí pues and no pues.[2] The question ¿pues no? of the classics corresponds to “of course”.[2] The Academy's dictionary lists the adverb “yes” and the obsolete “afterwards”.[4]
