Where Spanish comes from

Spanish is spoken Latin, reshaped by everyone it met: a pre-Roman substrate, Visigothic settlers, eight centuries of Arabic, Greek through three different doors, the languages of the Americas, and its own Romance cousins.

Etymology is not decoration. Knowing that stressed Latin Ŏ became ue explains every stem-changing verb; knowing that al- is a swallowed Arabic article explains a thousand words at once; knowing why leche and lácteo look unrelated turns the technical register into free vocabulary. This section traces the layers, from the Latin base to the newest anglicism.

The Latin core 6

Roughly three quarters of everyday Spanish descends from the spoken Latin of Roman Hispania — including the sound changes and the grammar shift that made it stop looking Latin.

Spanish is spoken Latin, not written Latin

Spanish descends from the everyday Latin of soldiers, traders and settlers in Hispania from 218 BC — which is why it says caballo and not equus, boca and not os.

Spanish among the Romance languages

Spanish is one of several daughters of spoken Latin, closest to Portuguese, Galician and Catalan. Any Romance language you already speak hands you thousands of Spanish words — plus a short list of traps.

From Latin to Spanish: the sound changes that did the work

A handful of regular changes turn most Latin words into their Spanish forms: F- → h-, stressed Ĕ → ie and Ŏ → ue, -CT- → -ch-, PL-/CL-/FL- → ll-, softened -p- -t- -c-, -NN- → ñ.

What became of Latin grammar: cases, articles and new tenses

Spanish dropped Latin's case endings and rebuilt what they did with prepositions and word order, invented articles out of demonstratives, and grew a whole compound-tense system out of haber — including the future.

Doublets: the same Latin word, borrowed twice

Hundreds of Latin words entered Spanish twice — once worn down by centuries of speech (llave, lleno, estrecho), once copied straight from books (clave, pleno, estricto). This is why so many Spanish adjectives look nothing like their nouns.

A timeline: from Latin to today's Spanish

Twenty-two centuries in one thread: Roman Hispania, the Visigothic kingdoms, al-Andalus, the rise of Castilian in the north, Alfonso X, Nebrija in 1492, the sibilant readjustment, the Academies, and a language whose centre of gravity is now American.

Layers of contact 4

What the peninsula spoke before Rome, what the Visigoths left behind, what eight centuries of al-Andalus contributed, and the three separate routes Greek took to get here.

Before Rome: Basque, Celtic and Iberian traces

Latin wiped out every pre-Roman language of the peninsula except Basque. What survives in Spanish is a few dozen words — izquierda, camino, cerveza, barro — one productive suffix, and almost all of the map.

The Germanic layer: Visigoths, war and names

A few hundred Germanic words reached Spanish — guerra, guardar, rico, blanco, ganar — plus the gu- spelling of Germanic w-, and the Visigothic first names behind Rodríguez, Fernández and González.

The Arabic layer: about 4,000 words

Eight centuries of al-Andalus made Arabic the second source of Spanish vocabulary after Latin. Its fingerprint is the swallowed article al-: almohada, alcalde, algodón — plus aceite, azúcar, ojalá and hasta.

Greek in Spanish: three different doors

Greek reached Spanish three times: worn down through Latin (iglesia, escuela, palabra), dressed in Arabic during the Middle Ages (alquimia), and coined fresh for science since the Renaissance (teléfono, psicología).

Beyond Europe, and the neighbours 3

The words Spanish borrowed once it crossed the Atlantic, plus the steady traffic with French, Italian, Catalan, Portuguese — and, since the twentieth century, English.
