Forms

espeso (feminine espesa, masculine plural espesos, feminine plural espesas)[1] Old Spanish wrote espesso, espessa beside espeso; the Diccionario de Autoridades still spelt it espesso.[2][3]

Etymology

It is inherited from Latin spissus (“thick, dense, compact”).[4][5] The Old Spanish form was espesso.[2][1]

The same Latin word is Portuguese espesso, Galician espeso, Asturian espesu, Catalan espès, Occitan espés, French épais, Italian spesso and Sardinian ispissu.[6][1][7] In Italian it also means “often”, a sense found in Old Catalan, Old Occitan and Old Spanish too.[6][8]

The Latin adjective meant first “slow, laborious” and then “dense”.[9][10] De Vaan reconstructs *spisso-, perhaps from *spid-to-, with the Greek family of Ancient Greek σπίδιος (spídios, “extensive, wide”) as its likeliest cognate; he notes that it may also contain an expressive double consonant, like crassus and grossus.[9] Wiktionary gives *spidtos (“thick and slow”).[1]

Earliest recorded meaning

The first record is the feminine espessa in a document of 1011 in the Colección diplomática de Oña.[2][4] In Alfonso X's Lapidario (1250–1279) a stone's whiteness is espessa, dense enough that the eye does not see through it.[11]

Semantic evolution

Old Spanish already used the adjective for a dense substance, for things growing close together, such as thick hair, and for a massive, solid body; the General Estoria has espesso uso in the sense “continual”.[11] The Diccionario de Autoridades gave the senses “condensed”, “thick, solid” and “close together”, illustrated with the dense wood of the Quijote.[3] The Academy's dictionary of 1843 lists the senses “frequent” and “dirty, greasy”, and marks “thick, massive” as old; the DLE now has “frequent” and “dirty” as little used.[12][5]

In Aragon, Peru and Venezuela espeso is said of a tiresome person, a sense the DAMER also gives for Guatemala, Cuba and Bolivia; in Ecuador, Argentina and Uruguay it describes a difficult, tense situation.[5][13] The historical dictionary of the Canaries records it in the sense “drunk”.[14]
