Most mistakes Spanish speakers make in English aren't random — they come directly from how Spanish grammar works. Once you see why a mistake happens, it's much easier to stop making it.
1. False friends
Spanish and English share a lot of Latin vocabulary, which is usually helpful — except when the words have drifted apart in meaning.
❌ I'm so embarrassed about the exam tomorrow. (meaning worried) ✅ I'm so nervous about the exam tomorrow.
Embarazada means "pregnant" in Spanish, not "embarrassed" — a classic trap.
❌ Actually, I live in Madrid. (meaning "currently") ✅ Currently, I live in Madrid. / Actually, I live in Madrid, not Barcelona. (meaning "in fact")
Actualmente means "currently," while English actually means "in fact" — the opposite kind of word.
2. Missing "do" in negatives and questions
Spanish doesn't need a helper verb to make a negative or a question — English almost always does.
❌ I no like coffee. ✅ I don't like coffee.
❌ You have a car? ✅ Do you have a car?
3. Dropping the subject pronoun
Spanish regularly drops the subject because the verb ending already shows who's doing the action (hablo clearly means "I speak"). English verbs don't carry that information, so the subject can't be dropped.
❌ Is raining today. ✅ It is raining today.
4. Adjective placement
In Spanish, adjectives usually come after the noun (una casa grande). In English, they almost always come before it.
❌ I bought a car red. ✅ I bought a red car.
5. "Make" vs "do"
Spanish uses one verb, hacer, for both. English splits it: make for creating something, do for performing an activity or task.
❌ I need to make my homework. ✅ I need to do my homework.
❌ Let's do a plan. ✅ Let's make a plan.
6. Prepositions of time
En covers a lot of ground in Spanish (en la mañana, en 2020) — English splits it into in, on, and at.
❌ I'll see you in Monday. ✅ I'll see you on Monday.
❌ The meeting is in 3 o'clock. ✅ The meeting is at 3 o'clock.
7. "Since" vs "for"
Both often translate to desde in Spanish, but English needs the right one depending on whether you're naming a starting point or a duration.
❌ I've lived here since five years. ✅ I've lived here for five years. (a duration) ✅ I've lived here since 2021. (a starting point)
