This is a list of Spanish words which are considered to be of Basque origin. Some of these words existed in Latin as loanwords from other languages. ^{[clarification needed]} Some of these words have alternate etymologies and may also appear on a list of Spanish words from a different language.

• abarca "sandal" (cf. Basque abarka < abar "branch", because they were originally made of branches). The word was loaned in Mozarabic and even in Arab pargha/bargha and from here to Spanish alpargata (Trask 2008, 74).
• abertzale / aberzale "Basque patriot, Basque nationalist" (cf. Basque abertzale). Recent loanword as it is a Basque neologism from the 19th century.
• agur "goodbye" (from Basque agur with the same meaning) (DRAE).
• aizcolari (cf. Basque aizkolari). Recent loanword.
• alud "avalanche (of snow)", from Basque elurte or uholde, olde "flood; avalanche" (Joan Corominas; DRAE); elurte is a blend of elur "snow" and lurte "landslide"^[1] (see lurte below).
• angula "elver (juvenile eel)", from Basque angula, from Lat anguilla "eel" (DRAE)
• aquelarre "witche's sabbath" (cf. Basque akelarre "goat field", fr. larre "field" and aker "billy goat")
• ardite "money of little value", fr. Basque dial. (Zuberoa) ardít "farthing", fr. Gascon (h)ardit, fr. English farthing (Monlau, Coromines).
• ascua "embers" (cf. Basque askuo, askua, fr. hauts "cinder")
• azcona "dart" (cf. Basque azkon "dart, javelin") (DRAE)
• barranco "ravine, deep gorge" (also Catalan barranc "cavity carved into rock by flowing water", Gascon/Occitan barenc "chasm"), from Basque barneko, barrenko "deep down, deep inside", from barren, barne "bottom, inside (noun)", superlatives of barru "inside, interior" (adj.).
• batúa (modern loanword from Basque)
• becerro "yearling calf", fr OSp bezerro "bullock" (cf. Basque bet- "cow" (combining form of behi) + -irru). Alternatively, Coromines (BDELC, 71) has OSp bezerro from *ibicirru, fr ibex, ibicis "mountain goat", although this is semantically and phonetically dubious (compare rebeco below).
• boina "beret". Modern (19th century) loanword from Basque. For the Basque word Coromines and Pascual (Trask 2008, 146) propose it came from Romance, from LL abonnis, obbonis "bandana, cap", supposedly from Gothic *obbundi, compound of *obe "above" and *bundi (cf. Old Saxon gibund "bundle").
• bruces, caer de "headlong, to fall". Uncertain. According to Coromines the original was "de buzos" / "de buces", which may be related with "bozo" (cf. "bozal"), which may come from Lat. bocca (through an hypothetical Romance *bucciu).
• cachorro "puppy" (metathesis of *chacorro < Basque txakur "whelp"); also Southern Corsican ghjacaru 'dog', Sardinian giagaru 'dog, hound'. Ousted now dialectal (rural Huesca) cadillo 'puppy', but in standard Spanish only having the sense of "bur-parsley".

• chamorro "close-cropped" (cf. Basque txamorro "grub, subterranean bug or worm" or samur, xamur "tender, delicate")
• chaparro "dwarf oak" (cf. Basque txapar)
• chaparrón. (Probably neither a pre-Roman word, nor a Basque loanword, but according to the DRAE it is an onomatopoeia; while Coromines believes that even Basque zaparr is an onomatopoeia).
• chapela, type of basque cap. Recent loanword (The Basque word is of Romance origin from Med. Latin capella).
• charro "crude", charrán "rogue, scamp" (cf. Basque txar "bad, faulty"; also Gascon charre "ignorant, naughty")

• sapo "toad" (also Gascon sapou, Aragonese zapo, Asturian sapu; cf. Basque zapo, apo). Rivals inherited escuerzo, from Lat scorteus "rough surface".
• sarna "scabies", from Medieval Latin (7th century, Isidore of Seville, Origines, 4.8.68), but as serna attested in Theodorus Priscianus (Constantinople, 4th century). Trumper,^[3] however, after studying the variants of the word in the Latin medical treatises, proposes a Hispano-Celtic origin; cf. Middle Welsh sarn "mess" and sarnaf "to wreck".^[4]
• sarro "tooth plaque" (cf. Basque sarra "rust") (Coromines, BDELC); however, DRAE derives it from Latin saburra "grit, sand", despite the fact this word actually gave sorra.
• silo "cave, granary pit" (cf. Basque zilo, zulo "hole" < Proto-Basque *süɫɦo); or, less likely, from Hispano-Celtic *silon "seed" (Coromines).
• socarrar "to scorch" (cf. Basque dial. and arch. sukarr(a) "flames, fire", fr. su "fire" and karr(a) "flame"

Koldo Mitxelena and modern form "senide" = 'brother or sister', 'relative')
