A common frustration for B2 learners in Spain: their grammar is fine, their vocabulary is wide, and yet every sentence comes out constructed. A Spaniard, by contrast, seems to start halfway through — Lo que pasa es que…, No es que…, Por más que…, Que yo sepa… — and only then begins thinking about content. The difference is prefabricated scaffolding: native speakers carry a stock of fixed sentence frames, skeletons with open slots they fill on the fly.
Frames are different from idioms. Estar en las nubes (to daydream) is a chunk you memorise whole. Lo que pasa es que… is a frame — its job is to launch a sentence whose contents are up to you. The skeleton is fixed; the slot is free. This page maps the most important frames in peninsular Spanish, organised by function.
Fixed frames vs. free combinations
A free combination is built with productive grammar: La verdad es que tengo hambre is assembled from available parts. A fixed frame has idiomatic status — speakers recognise it as a unit and notice if you swap in a near-synonym. The diagnostic is substitution: Lo que pasa es que… exists; La cosa es que… sounds Latin-American to a peninsular ear despite being grammatically impeccable. El caso es que… exists; Lo que ocurre es que… sounds stilted. Substitution breaks the skeleton.
Family 1: Explaining and justifying
These frames signal "I am about to tell you why" — the most-used family in spoken Spanish, often following an apology or a refusal.
Lo que pasa es que…
The default explanatory opener in Spain — soft, non-confrontational, slightly defensive, more often a lead-in to an excuse than to a neutral explanation.
Lo que pasa es que no me apetece nada salir esta noche, de verdad.
The thing is, I really don't feel like going out tonight.
Lo que pasa es que mi madre llega el viernes y tengo la casa hecha un desastre.
The thing is, my mum arrives on Friday and the flat is an absolute mess.
Lo que pasa es que el cuñado de Marta se ha quedado sin curro y la cosa está chunga.
The thing is, Marta's brother-in-law has just lost his job and things are rough.
El caso es que…
More neutral than lo que pasa es que — no apology, just narration. The natural way to land a story's punchline.
Total, que el caso es que al final acabamos cenando en el chino de abajo.
Anyway, the upshot is that we ended up having dinner at the Chinese place downstairs.
El caso es que nadie le había avisado y se presentó allí sin saber nada.
The fact is, nobody had warned him and he turned up there with no idea what was going on.
Es que…
The stripped-down version — the bare minimum of lo que pasa es que, with strong excuse-making overtones. See also Es que.
—¿No vienes? —Es que mañana madrugo un montón.
—Aren't you coming? —It's just that I have to get up really early tomorrow.
—¿Por qué no se lo has dicho? —Es que me daba un poco de corte.
—Why didn't you tell him? —It's just that I felt a bit awkward about it.
Family 2: Reporting on hearsay and evidence
These frames mark the speaker's epistemic position — how they came to know what they are saying.
Por lo visto…
"Apparently / from what I can see." Reports something the speaker heard or inferred rather than witnessed — constant in gossip and news commentary.
Por lo visto, han despedido a media plantilla.
Apparently they've sacked half the staff.
Por lo visto, el bar de la esquina cierra a final de mes.
From what I hear, the corner bar is closing at the end of the month.
No fui a la reunión, pero por lo visto fue un desastre.
I didn't go to the meeting, but apparently it was a disaster.
Que yo sepa…
"As far as I know." Hedges a claim as the speaker's best knowledge. The verb is always in the subjunctive (sepa, recuerde, vea) — que here introduces a relative clause inside the limit ("from the set of things I am aware of").
Que yo sepa, todavía no han publicado las notas.
As far as I know, they haven't put up the grades yet.
No tiene pareja, que yo sepa.
He doesn't have a partner, as far as I know.
Que yo recuerde, nunca hemos tenido un problema así.
As far as I can remember, we've never had a problem like this.
Si te digo la verdad… / La verdad es que…
Flag candor — what follows is the honest answer, possibly contrary to expectation.
Si te digo la verdad, la película no me gustó nada.
To be honest with you, I didn't like the film at all.
La verdad es que no me veo currando allí más de un año.
Honestly, I don't see myself working there more than a year.
Family 3: Conceding and qualifying
A rich set of frames for conceding a point — acknowledging an objection before pivoting against it.
No es que… sino que…
A two-part frame that denies one interpretation and substitutes another. The clause after no es que takes the subjunctive (the interpretation is being negated); the clause after sino que takes the indicative (it is being asserted).
No es que no quiera ayudarte, sino que ahora mismo no tengo un duro.
It's not that I don't want to help you — it's that right now I'm flat broke.
No es que sea mala persona, sino que tiene un día malo.
It's not that he's a bad person — it's that he's having a rough day.
No es que el plan sea malo, sino que no es realista.
It's not that the plan is bad — it's that it isn't realistic.
Por más que… (no)…
"However much / no matter how much." Takes the subjunctive when hypothetical or persistent. Concedes maximum effort, then reports failure.
Por más que se lo explico, no lo entiende.
No matter how many times I explain it to him, he doesn't get it.
Por más que insistas, no voy a cambiar de opinión.
However much you push, I'm not going to change my mind.
Por más que lo intento, no me sale la receta como a mi abuela.
No matter how hard I try, I can't get the recipe to come out like my grandma's.
Y eso que…
A peculiarly Spanish concessive frame — "and that's even though" — adds a fact that should have prevented the outcome just described. No clean English equivalent.
Llegamos empapados, y eso que llevábamos paraguas.
We arrived soaked — and that's despite having umbrellas.
Suspendió el examen, y eso que se había pasado toda la semana estudiando.
He failed the exam — and that's after spending the whole week studying.
Está agotada, y eso que ayer durmió diez horas.
She's exhausted — and that's after sleeping ten hours yesterday.
Family 4: Topic-launching and meta-talk
These open turns, redirect attention, or comment on the conversation itself.
Vamos a ver, …
"Let's see / hold on a minute." Used to slow the conversation down before correcting or clarifying. Very peninsular — a Spaniard who feels the discussion is going off the rails will reach for this every time.
Vamos a ver, ¿qué es exactamente lo que ha pasado?
Hold on a second — what exactly happened?
Vamos a ver, no os pongáis nerviosos, hay tiempo de sobra.
OK, let's all calm down, there's plenty of time.
Eso de + INF + es + ADJ
Evaluates a generic activity. The infinitive phrase ("the thing of doing X") is treated as a noun.
Eso de madrugar para ir al gimnasio es de locos.
That whole getting-up-early-to-go-to-the-gym thing is crazy.
Eso de trabajar desde casa tiene sus cosas buenas y sus cosas malas.
This working-from-home thing has its upsides and downsides.
Eso de comer cinco veces al día no es para todo el mundo.
The whole eating-five-times-a-day thing isn't for everyone.
No te vayas a creer que… / No os vayáis a creer que…
Pre-empts a wrong inference — "don't go thinking that…". The peninsular vosotros form is no os vayáis a creer.
No te vayas a creer que es fácil, eh, esto cuesta lo suyo.
Don't go thinking this is easy — it takes real work.
No os vayáis a creer que estoy enfadado, solo estoy cansado.
Don't you all start thinking I'm angry — I'm just tired.
En cuanto a… / En lo que respecta a…
Topic introducers. En cuanto a works in speech and writing; en lo que respecta a leans formal — common in bureaucratic and journalistic registers.
En cuanto a las vacaciones, todavía no hemos decidido nada.
As for the holidays, we haven't decided anything yet.
En lo que respecta a la subida del IVA, el ministro ha sido claro.
As regards the VAT hike, the minister has been clear.
What the slots accept — mood reference
Each frame restricts what can fill its slot. The mood is often the trip wire.
| Frame | Slot takes | Why |
|---|---|---|
| Lo que pasa es que… | indicative | Asserts a fact |
| El caso es que… | indicative | Asserts a fact |
| No es que… | subjunctive | Denies a state of affairs |
| …sino que… | indicative | Asserts a fact |
| Por más que… | subjunctive (or indicative if real) | Concedes a hypothetical or persistent effort |
| Que yo sepa… | (verb inside is subjunctive: sepa) | Relative clause inside an evidential |
| No te vayas a creer que… | indicative or subjunctive | Indicative for the false belief; subjunctive when stronger |
| Por lo visto… | indicative | Reports a hearsay claim |
| Y eso que… | indicative | Adds a real, conceded fact |
Comparison with English
English has sentence frames too (the thing is, as far as I know) but Spanish leans on them more heavily. The biggest gap is evidentiality: English manages with apparently and I think, while Spanish has por lo visto, al parecer, que yo sepa, si no me equivoco, según parece. Without them your Spanish sounds oddly assertive — every claim presented as bald fact.
A mini-dialogue using frames
—¿Te has enterado de lo de Pablo? —¿Lo del trabajo? Por lo visto le han ascendido. —Hombre, no me extraña, lleva currando allí cinco años. —Vamos a ver, no es que no se lo merezca, sino que pensaba que iban a coger a otro. Y eso que él se lo había currado mucho. —Pues que yo sepa, todavía no es oficial. —Lo que pasa es que en esa empresa estas cosas tardan mil años.
—Have you heard about Pablo? —The work thing? Apparently he's been promoted. —Well, no wonder, he's been working there five years. —Hold on, it's not that he doesn't deserve it, it's that I thought they were going to pick someone else. Even though he'd put in the work. —Well, as far as I know it's not official yet. —The thing is, in that company these things take forever.
Common mistakes
❌ No es que no quiero ir, es que no puedo.
Attempted: It's not that I don't want to go, it's that I can't. (No es que requires the subjunctive: quiera.)
✅ No es que no quiera ir, es que no puedo.
It's not that I don't want to go — it's that I can't.
❌ Que yo sé, todavía no han llegado.
Attempted: As far as I know, they haven't arrived yet. (Que yo sepa takes the subjunctive — it's a fixed frame.)
✅ Que yo sepa, todavía no han llegado.
As far as I know, they haven't arrived yet.
❌ La cosa es que no tengo tiempo.
Attempted: The thing is, I don't have time. (Understood but Latin-American flavoured; in Spain say lo que pasa es que or el caso es que.)
✅ Lo que pasa es que no tengo tiempo.
The thing is, I don't have time.
❌ Por más que se lo explico, no entiende.
Attempted: No matter how much I explain it, he doesn't understand. (Missing the object pronoun lo: no lo entiende.)
✅ Por más que se lo explico, no lo entiende.
No matter how much I explain it to him, he doesn't get it.
❌ Y eso de que llevaba paraguas, llegué empapado.
Attempted: Even though I had an umbrella, I arrived soaked. (Y eso que — no de.)
✅ Llegué empapado, y eso que llevaba paraguas.
I arrived soaked — even though I had an umbrella.
Key takeaways
- Frames are templates with open slots, not idioms. The skeleton is fixed; the slot is free.
- The most-used families in peninsular Spanish are explanation (lo que pasa es que, el caso es que, es que), evidentiality (por lo visto, que yo sepa), concession (no es que… sino que…, por más que…, y eso que), and meta-talk (vamos a ver, eso de + INF, no te vayas a creer que).
- Watch the mood: no es que
- subjunctive, por más que
- subjunctive, que yo sepa with subjunctive sepa.
- subjunctive, por más que
- The highest-payoff frame for an English speaker is y eso que — no clean English equivalent.
