Can you learn Spanish and Italian at the same time?
In short
- Yes, with a clear strategy. The two languages are alike (Ethnologue puts their lexical similarity at 82%, on a list of basic words), which helps with vocabulary and invites mix-ups.
- Mix-ups are most likely at the beginning, in false friends, prepositions and articles, and auxiliary verbs.
- Four principles kept them apart: each language’s sound first, its own cultural words, grammar through usage, and thinking directly in the language.
- Consider building a solid base in one language first (around B1), or give each language its own time, place or medium.
- In the author’s experience, short, frequent contact through the day works better than long, infrequent sessions.
Yes, you can learn Spanish and Italian at the same time, but it takes a clear strategy to manage how alike they are.
Ethnologue puts the lexical similarity of Spanish and Italian at 82%, measured on a standard list of basic words.1 That gives you a huge head start on vocabulary when you learn both, and a real risk of mixing up their words and grammar. Success comes down to giving each language its own identity in your mind, mastering pronunciation early, and staggering where you start.
My reason
When I was sixteen, having already spent years learning French and Spanish at school, I decided to take on Italian as well. I had enjoyed learning French and Spanish, but I had a family reason for learning Italian: my paternal ancestry came from mainland Italy, Sicily and Malta. I went on to study French, Spanish and Italian for my university degree, which meant four years of listening, reading, writing and speaking, and latterly translating and interpreting, all three side by side.
People often asked me whether, as a native English speaker, I got confused. The short answer is yes, occasionally, but far less than you might expect. The Romance languages share a common Latin foundation, but each has its own internal logic, cadence and feel. In my opinion, learning to navigate those boundaries is the secret to keeping them separate in your head.
On paper, the similarities between Spanish and Italian are obvious. “The university is important for the future” becomes La universidad es importante para el futuro in Spanish and L’università è importante per il futuro in Italian. As a learner, that overlap feels like finding a cheat code. English words ending in “-tion” (station) often end in -ción in Spanish (estación) and -zione in Italian (stazione). But if you rely on guesswork, the same similarity can trip you up just as quickly.
Will I mix up Spanish and Italian?
The short answer is yes, especially at the beginning, when both languages are least familiar. When two languages share so much DNA, your brain naturally fills the gaps in one by borrowing from the other.
In linguistics this is called cross-linguistic interference. In practice, it means slipping into a hybrid of the two when you are tired or tongue-tied. If you have ever heard someone speak “Itañol”, or its Spanish–Portuguese cousin “Portuñol”, you have heard it in action.
The confusion usually shows up in three places.
False friends
False friends (falsos amigos, falsi amici) are words that look or sound alike but mean different things. Burro means “donkey” in Spanish and burro means “butter” in Italian. Spanish subir means “to go up”, while Italian subire means “to suffer” or “to undergo”. Ask a Spanish host for burro on your bread, with the Italian word in mind, and you might get a funny look.
Prepositions and articles
Spanish uses en for location (“in” or “on”), whereas Italian uses in or a, often fused with the article into forms like nel or nella. Switching between Spanish en la calle and Italian per strada or in strada (“in the street”) takes conscious effort.
Auxiliary verbs
Both languages have compound past tenses, but Italian, like French, makes you choose between avere (“to have”) and essere (“to be”) depending on the verb. Spanish settled this long ago by using haber for every compound tense. A Spanish speaker might instinctively say ho andato in Italian, where an Italian ear expects sono andato.
What helped me stop mixing them up?
During my degree, I noticed that the learners who struggled most were the ones who treated vocabulary as lists of English translations. To stop mixing up Spanish and Italian, you have to anchor each language to its own sounds and its own structure.
Here are four principles that kept my Spanish and Italian apart.
Master the alphabet and the sound of each language first
Before memorising long vocabulary lists, spend time practising the sounds of each language. Spanish has a clean, crisp system of five vowels, a rolled rr, and the throaty j of jabón. Italian has open and closed forms of its e and o, double consonants (doppie), and a melodic rhythm all its own.
One of my Italian oral teachers at university told us again and again, L’italiano è una melodia! (“Italian is a melody!”), and would sometimes take a student’s face in both hands to coax the words out in the right cadence.
Once you can feel the sound of Italian, a Spanish sound in an Italian sentence starts to feel wrong, and the same happens the other way round. Italian double consonants, as in gatto or bellissimo, are held a moment longer, a lengthening Spanish barely has. Tuning your ear to these acoustic fingerprints builds a stronger and stronger mental firewall.
Focus on cultural words
When you study two languages, many of the words that matter most belong to one culture. In Spain, you will talk about tapas, cañas and the Renfe trains. In Italy, you will meet aperitivo, espresso and Trenitalia. Words tied to a real place make strong mental anchors, and they keep the two languages from bleeding into each other.
This principle shaped how we built the word banks in the Lumessa app: each language’s vocabulary is tailored to its own country and culture, and the words tied to your reason for learning come sooner.
Learn grammar through usage, not rules
Native speakers do not run through conjugation tables before they open their mouths. They pattern-match, through constant use.
Learning parallel grammar rules for Spanish and Italian side by side invites confusion. Focus instead on complete, idiomatic expressions. Rather than memorising how the Italian passato prossimo differs from the Spanish pretérito perfecto, learn whole phrases tied to actions. With enough exposure, ho andato will simply sound wrong to you, without your needing to analyse why. In my experience, that is a more natural, and ultimately more efficient, way to learn a foreign grammar.
Never translate in your head
A common mistake is to think in English first and then translate, word for word, into Spanish or Italian. When you are learning both at once, that route through English, into one of two similar languages, is where the gridlock sets in.
Train yourself to think directly in the language you are speaking, connecting words straight to things and images rather than to English. Linking the Italian macchina directly to the picture of a car, rather than routing it through the English word “car”, helps each language build its own network in your mind.
Should you start both at exactly the same time?
If you are starting from zero in both, learning them together from day one is possible, but I would suggest staggering them to make the process smoother.
A solid base in one language first, around B1, the intermediate level, gives you a stable reference point. Once your Spanish vocabulary and grammar are firmly established, starting Italian feels less like starting from scratch and more like a variation on a familiar theme – rather like learning new algebra built on equations you already know. You can make the most of the overlap between the two without constantly undermining the language you started with.
If you do study both at once, try giving each language its own time or place. Study Italian in the morning over an espresso, and Spanish in the evening over a glass of sangria. Or use a different medium for each: read the news in Spanish and listen to podcasts in Italian. It helps keep the languages apart in your mind, and ideally ties each one to its own culture too.
How to structure your daily practice
Consistency and repetition are what make a new language stick. With two languages to manage, I have found long, infrequent study sessions far less effective than short, frequent contact throughout the day.
Repetition happens naturally when you live in the country. When you are learning on your own, especially from abroad, artificial repetition helps bridge the gap. That is why we built a lock screen widget into the Lumessa app: it shows the words you are learning on your phone throughout the day, so you meet them again and again in everyday life.
The path to fluency in both
Learning Spanish and Italian together is a rewarding undertaking. The shared vocabulary will lead to the occasional mix-up, but the same closeness gives you quick access to two rich cultures, literatures and histories.
Get the sound of each language first, anchor your vocabulary in each culture, learn grammar through usage, and think directly in the language you are speaking. That is how I built a separate path to each, and it is how I would start again.
