Latin, Arabic, indigenous and English layers — and reading a word you have never seen
C2 is not defined by knowing more words. It is defined by not being stopped by unfamiliar ones — by reading pusilánime or alborotar or soslayar for the first time and getting most of the way there from the shape of the word alone.
That skill comes from knowing where Spanish words come from. Spanish is Latin that spent seven hundred years alongside Arabic, then crossed an ocean and absorbed Nahuatl, Quechua and Taíno, with Greek, Germanic, French, Italian and English layered on at various points. Each layer left a fingerprint. Learn the fingerprints and vocabulary stops being a list to memorise and becomes a system to read.
Words inherited orally from spoken Latin ("patrimoniales") changed in regular ways. Six rules cover most of it:
| Latin | → Spanish | Examples |
|---|---|---|
| F- at the start | h- (silent) | FACERE → hacer; FERRUM → hierro; FILIUM → hijo; FUMUM → humo |
| PL-, CL-, FL- | ll- | PLUVIA → lluvia; CLAMARE → llamar; FLAMMA → llama; PLENUM → lleno |
| -CT- | -ch- | NOCTEM → noche; FACTUM → hecho; LACTEM → leche; OCTO → ocho |
| Short E | ie | PETRAM → piedra; TERRAM → tierra; FERRUM → hierro |
| Short O | ue | PORTAM → puerta; MORTEM → muerte; NOVEM → nueve |
| -LI-, -CUL- | -j- | FILIUM → hijo; OCULUM → ojo; APICULAM → abeja |
Many Latin words entered Spanish twice: once orally (worn down by the sound laws) and once later, borrowed straight from written Latin by scholars — a cultismo, barely changed. The pair survives with split meanings and, crucially, split registers.
| Latin | Patrimonial (oral) | Cultismo (learned) |
|---|---|---|
| CLAVEM | llave (key) | clave (key, code, crucial) |
| COLLOCARE | colgar (to hang) | colocar (to place) |
| DELICATUM | delgado (thin) | delicado (delicate) |
| STRICTUM | estrecho (narrow) | estricto (strict) |
| CATHEDRAM | cadera (hip) | cátedra (professorship) |
| OPERARI | obrar (to act) | operar (to operate) |
| DIGITALEM | dedal (thimble) | digital |
| LAICUM | lego (layman) | laico (secular) |
| FABRICARE | fraguar (to forge, hatch) | fabricar (to manufacture) |
Why this matters for writing: the cultismo is almost always the higher register. Ocular vs del ojo; pluvial vs de lluvia; fraternal vs de hermanos; auricular vs de la oreja. When you need to raise the register of a phrase, reach for the Latin adjective.
| Everyday noun | Learned adjective |
|---|---|
| ojo | ocular |
| hígado | hepático |
| hueso | óseo |
| leche | lácteo |
| hijo | filial |
| agua | acuático / hídrico |
| noche | nocturno |
| hierro | férreo |
Al-Andalus lasted from 711 to 1492. Spanish took roughly four thousand words from Arabic — more than from any source except Latin. The layer is instantly recognisable: most of it begins with al-, the Arabic definite article, fused onto the noun.
| Field | Words |
|---|---|
| Administration & law | alcalde (mayor), alguacil, aduana, albacea, tarifa, arancel |
| Agriculture & irrigation | acequia, aljibe, noria, azud, alberca, algodón, azúcar, aceite, aceituna, arroz, naranja, limón, zanahoria, berenjena, alcachofa, albaricoque, sandía |
| House & building | almohada, alfombra, azulejo, alcoba, zaguán, albañil, azotea, alacena, tabique, rincón |
| Science & maths | álgebra, algoritmo, cifra, cero, alcohol, alquimia, alambique, auge, nadir, cenit |
| War | alcázar, atalaya, alférez, jinete, rehén, alarde |
| Everyday | ojalá, hasta, fulano, mezquino, barrio, tarea, ajedrez, azar, hazaña, asesino, resaca |
After 1492 Spanish absorbed thousands of words from indigenous American languages — many of which then travelled into English and the rest of the world.
| Source | Where | Words |
|---|---|---|
| Náhuatl | Central Mexico | chocolate, tomate, aguacate, chile, cacahuate, chicle, coyote, ocelote, petate, jícara, tiza, cuate, elote, mezcal |
| Quechua | Andes | papa, cóndor, puma, llama, vicuña, pampa, cancha, carpa, guano, chacra, choclo, soroche, mate, quinua |
| Taíno / Arahuaco | Caribbean (the first contact) | canoa, huracán, hamaca, maíz, tabaco, barbacoa, caimán, iguana, cacique, ají, yuca, sabana |
| Guaraní | Paraguay, NE Argentina | jaguar, tapioca, ñandú, tucán, yacaré, mandioca |
| Mapudungun | Chile | poncho, malón, laucha, pilcha |
Taíno words entered first and therefore became pan-Hispanic — canoa and huracán are used in Madrid. Nahuatl and Quechua words are often regional, which is exactly why palta (Quechua) and aguacate (Nahuatl) split the continent, as Lesson 8 showed.
| Source | Period | Words |
|---|---|---|
| Germanic (Visigothic) | 5th–8th c. | guerra, guardia, ganar, rico, blanco, orgullo, espuela, yelmo, ropa, and the -ez surnames (Rodríguez = son of Rodrigo) |
| Greek (via Latin, then learned coinage) | all periods | All of science: psico-, bio-, geo-, tele-, crono-, demo-, -logía, -grafía, -metro, -itis, -filia, -fobia |
| French | 18th–19th c. | jardín, jefe, mensaje, garaje, chofer, hotel, restaurante, bufanda, debut, carné, chalé |
| Italian | Renaissance | soneto, novela, piano, banca, escopeta, capricho, fachada, charlar, esbelto |
| English | 20th–21st c. | fútbol, líder, estrés, escáner, bistec, vagón, tuit, wifi, chatear, formatear, clicar |
Take it apart. Prefix + root + suffix, and the layer tells you the register.
| Prefix | Sense | Example |
|---|---|---|
| in- / im- / i- | not | inefable, imberbe, ilícito |
| des- / dis- | reversal, lack | desdecirse, disconforme |
| sub- / so- | under | subyacer, socavar |
| sobre- / super- | over | sobrellevar, superar |
| entre- / inter- | between | entrever, interponer |
| contra- / anti- | against | contraponer, antagónico |
| pre- / ante- | before | prever, antedicho |
| re- | again, intensely | rehacer, requeteguapo |
| ex- / extra- | out of, beyond | exánime, extralimitarse |
Worked examples.
soslayar — so- (under) + slayo/soslayo (sideways) → to sidestep, to dodge an issue.
pusilánime — Latin pusillus (tiny) + animus (spirit) → faint-hearted, cowardly.
entrever — entre (between) + ver → to glimpse, to half-see.
desdecirse — des- (undo) + decirse → to retract what one said.
inefable — in- + ef- (Latin fari, to speak) + -able → unspeakable, beyond words.

You can now read a word you have never met. The next question is whether you can write the words you know without a single slip — accents, punctuation, capitals and the handful of homophone pairs that catch even educated natives. Lesson 14 turns you into your own proofreader.
