Error Doctor
Catch the errors that survived into fluency — and fix them yourself, mid-sentence, out loud.
The errors that survive into advanced Spanish are fossilized, not random — and they cluster. False cognates: realizar means carry out, not realize (that's darse cuenta de); actualmente means currently, not actually (en realidad); asistir a means attend, not assist. Prepositional drift: it's depende de, soñar con, pensar en — the wrong preposition feels right but isn't. And the dodged subjunctive: espero que llegues (never espero que llegas) and cuando llegues, avísame for anything still pending — while the reverse trap, hypercorrection, makes creo que tiene razón the right answer, indicative and all.
Below: the repairs phrase by phrase, the calques that mark you as translated — and a way to practice catching them the only way self-correction sticks: mid-conversation, out loud, not on a worksheet.
The warm-up pack
The mistakes that survive into fluent Spanish — caught and fixed mid-sentence, out loud.
01 · "Realizar" doesn't mean realize
Voy a realizar un estudio de mercado.
I am going to carry out a market study.
'Realizar' means carry out, not realize — say this about a market study, not about a sudden realization. It fixes one very common, very fossilized mix-up.
02 · The verb that actually means "realize"
Me di cuenta de que había olvidado las llaves.
I realized I had forgotten the keys.
This is the verb English speakers actually want when they reach for 'realizar' — 'darse cuenta de' is what 'realize' really means.
03 · "Actualmente" isn't "actually"
Actualmente trabajo en una consultora.
I currently work at a consultancy.
'Actualmente' means currently, not actually — this sentence is safe; reach for 'en realidad' when you mean 'actually.'
04 · "En," never "de"
Consiste en tres etapas bien definidas.
It consists of three well-defined stages.
'Consiste EN,' never 'consiste DE' — the wrong preposition here is the kind of error that survives years into fluent Spanish because it just feels right.
05 · What you dream "con," not "de"
Soñé con un viaje a la Patagonia.
I dreamt of a trip to Patagonia.
'Soñé CON,' not 'soñé DE' — prepositions attach to the verb, not the meaning, so you have to learn the pairing, not guess it.
06 · Doubt drags the mood down with it
Dudo que sea verdad lo que cuentan.
I doubt what they say is true.
'Dudo QUE' pulls the next verb into subjunctive automatically — doubt is one of the triggers that never lets the indicative slide through.
07 · Glad triggers subjunctive too
Me alegra que hayas venido.
I am glad you have come.
It's not just wishing and doubting — being glad triggers subjunctive too. 'Me alegra que hayas venido,' never 'que has venido.'
08 · "As soon as" still isn't finished yet
En cuanto termine la reunión, te llamo.
As soon as the meeting ends, I will call you.
The meeting hasn't ended yet when you say this — that's exactly why 'termine' is subjunctive and not 'termina.' Pending, not habitual.
09 · Before it happens, it's still subjunctive
Antes de que se haga tarde, salgamos.
Before it gets late, let us leave.
Anything framed with 'antes de que' is inherently not-yet-happened, so the subjunctive is automatic here, no exceptions to memorize.
10 · When the plain form is the right one
Es verdad que vino ayer.
It is true that he came yesterday.
This one takes indicative, not subjunctive — 'es verdad que vino,' not 'que viniera.' Overcorrecting into subjunctive here is the trap advanced learners fall into.
11 · The sense-making calque nobody catches
Eso no tiene sentido.
That does not make sense.
'Eso no tiene sentido,' never 'hace sentido' — that's an English calque that creeps in exactly because the wrong version sounds so plausible.

Carla
Your grammar teacher for this pack
No error lists to memorize, no gap-fills. In the Error Doctor lessons you talk, and Carla hands you your own fossils to repair in real time: she feeds you sentences with realizar, asistir and actualmente used English-style and you fix them to native Spanish; she makes you produce the right preposition for pensar, soñar and depender with no model to lean on; then she shows you creo que tiene razón next to creo que tenga razón and asks which one a native would actually say — and why. Out loud, until you catch the slip before she does.
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.

Quick answers
No. Realizar means to carry out: voy a realizar un estudio de mercado. To realize something is darse cuenta de: me di cuenta de que había olvidado las llaves.
Depende de, always: depende de la situación, no de ti. The same drift hits other verbs — it's soñé con un viaje (not de), consiste en tres etapas (not de), se parece a su padre (not como).
No — it's a calque from English 'make sense'. Say eso no tiene sentido. Same family: llevo diez años viviendo aquí beats the translated-sounding he estado viviendo aquí por diez años.
Espero que llegues — hope, doubt and emotion verbs take the subjunctive: dudo que sea verdad, me alegra que hayas venido. Future-referring time clauses too: cuando llegues, avísame, never cuando llegas.
Reaching for the 'more Spanish-looking' form when the simple one is right. Affirmative opinion and knowledge take the indicative: creo que tiene razón, sé que están ocupados hoy — forcing the subjunctive there is itself the error, one C1 students make constantly.
