A huge slice of the Spanish verb system comes in two flavours: the bare form (ir, comer, dormir, quedar, llevar) and the reflexive form with se attached (irse, comerse, dormirse, quedarse, llevarse). To an English speaker they often look like the same verb — but they are not. Ir and irse both translate as to go, yet a Spaniard reaching for me voy rather than voy is doing something specific with meaning. The reflexive isn't a stylistic accessory; it changes aspect, intensity, completion, or focus.
This page maps the systematic differences: aspectual reflexives that mark completion (comerse, beberse), change-of-state reflexives that mark transitions (dormirse, ponerse), inherently reflexive verbs with no non-reflexive counterpart (arrepentirse, atreverse), and the cases where adding or dropping the se makes the sentence ungrammatical.
Three things se can be doing
Before the verb pairs, sort out what the se (or me / te / nos / os) is doing in any given sentence. There are three live functions, and they're often confused.
- True reflexive: the subject acts on itself. Me lavo = I wash myself. The action loops back to the doer.
- Reciprocal: two or more subjects act on each other. Se miraron = they looked at each other.
- Pronominal / aspectual / change-of-state se: the se is attached lexically; the verb means something specific with it that it doesn't mean without it. Me arrepiento (I regret), me caigo (I fall over), me como una manzana (I eat up an apple). This is the se this page is mostly about.
The first two are predictable and look like English reflexives and reciprocals. The third is the one that creates the verb pairs and that English has no morphological way to mark.
Aspectual se: completion and intensity
Verbs of consumption (comer, beber, fumar, leer, tomar, tragar) gain a reflexive form that marks the action as complete and the object as fully consumed. The bare verb describes the activity; the reflexive describes the polished-off result.
Estoy comiendo una manzana.
I'm eating an apple. (Activity in progress — bare verb.)
Me he comido una manzana entera del tirón.
I ate a whole apple in one go. (Completed, all of it — reflexive.)
Bebo agua todos los días.
I drink water every day. (Generic activity.)
Se bebió la botella entera él solo.
He drank the whole bottle by himself. (Completion + slight emphasis.)
Me leí los tres libros en una semana.
I plowed through all three books in a week. (Reading-through, finished.)
The reflexive form requires a determinate, bounded object — una manzana entera, la botella, los tres libros. It does not work with mass nouns or indeterminate quantities. Me bebo agua is wrong; me bebo un vaso de agua is fine. The completion se needs something to complete.
The aspectual se also adds subtle emphasis: me comí tres bocadillos is slightly more vivid than the neutral comí tres bocadillos — the difference between I ate three sandwiches and I downed three sandwiches.
Change-of-state se: dormir vs dormirse, ir vs irse
A second family marks a change of state. The bare verb describes the state; the reflexive describes the moment of entering the state.
| Bare verb | Reflexive | Shift |
|---|---|---|
| dormir (to sleep) | dormirse (to fall asleep) | state → entering it |
| ir (to go) | irse (to leave, go away) | motion → departure |
| quedar (to remain) | quedarse (to stay) | be left → choose to stay |
| llevar (to carry) | llevarse (to take away) | carry → take with you |
| caer (to fall) | caerse (to fall over) | downward motion → accidental fall |
| ver (to see) | verse (to meet up, look) | see → meet / appear |
| encontrar (to find) | encontrarse (to be located / feel) | find → be in a state |
| parecer (to seem) | parecerse (to resemble) | seem → look like |
Mi hijo duerme ocho horas por la noche.
My son sleeps eight hours a night. (Ongoing state of sleep.)
Se durmió en el sofá viendo la tele.
He fell asleep on the sofa watching TV. (The moment of falling asleep.)
Voy al trabajo en metro todos los días.
I go to work by metro every day. (Direction-focused motion.)
Me voy, ya hablamos mañana.
I'm off, we'll talk tomorrow. (Departure-focused.)
¿Te quedas o te vienes?
Are you staying or coming along?
Se cayó por las escaleras y se rompió el tobillo.
He fell down the stairs and broke his ankle.
The ir / irse contrast is the one that catches most learners. Voy a casa = I'm going home (in transit, focus on destination). Me voy a casa = I'm leaving for home (focus on the departure from where I am now). Spaniards use irse constantly to mark the moment of leaving — me voy, nos vamos ya, vete a la cama, que se vaya.
¿Te encuentras bien? Tienes mala cara.
Are you feeling alright? You look unwell. (encontrarse = to feel.)
Te pareces mucho a tu padre.
You look a lot like your father. (parecerse = to resemble.)
Se of becoming: ponerse, hacerse, volverse, quedarse
Spanish has no single verb for to become. Instead, a family of reflexive verbs each handles a particular shade of becoming.
| Verb | Type of change | Example |
|---|---|---|
| ponerse | Temporary state, often emotional or physical | Se puso rojo de la vergüenza. |
volverse
| Sudden or unwilled change in personality / state | Se ha vuelto muy quisquillosa últimamente. |
hacerse
| Gradual change, often through effort or choice | Se hizo abogado a los treinta. |
quedarse
| Result of an event; ended up in a state | Me quedé sin batería en mitad de la llamada. |
convertirse en
| Transformation into something different | Madrid se ha convertido en una ciudad carísima. |
llegar a ser
| Achievement after effort | Llegó a ser el mejor cirujano del país. |
Me pongo nerviosa cuando hablo en público.
I get nervous when I speak in public. (Temporary emotional state — ponerse.)
Se ha hecho rico vendiendo pisos en la costa.
He's gotten rich selling flats on the coast. (Achievement — hacerse.)
Después del divorcio se volvió muy desconfiado.
After the divorce he became very suspicious. (Change in personality — volverse.)
Me quedé en blanco en mitad del examen.
I went blank in the middle of the exam. (Ended up in a state — quedarse.)
Spanish has no other way to say to become. Learn the four core verbs (ponerse, volverse, hacerse, quedarse) and the noun-shift convertirse en and you'll cover almost every case.
Inherently reflexive verbs: no bare form exists
Some Spanish verbs only exist with se — there is no non-reflexive form. These describe psychological states or reactions and take various prepositional complements you have to learn with them.
| Verb | Meaning | Preposition |
|---|---|---|
| arrepentirse | to regret | de |
| atreverse | to dare | a |
| quejarse | to complain | de |
| burlarse | to make fun of | de |
| jactarse | to boast | de |
| fugarse | to flee / run away | de |
| suicidarse | to commit suicide | — |
| esforzarse | to make an effort | por / en |
| abstenerse | to abstain | de |
| desmayarse | to faint | — |
Me arrepiento de no haber estudiado más.
I regret not having studied more.
No me atrevo a decírselo a su madre.
I don't dare tell his mother.
Siempre se queja del ruido del vecino de arriba.
He always complains about the noise from the upstairs neighbour.
These verbs cannot drop the pronoun. Arrepiento de no haber estudiado más is ungrammatical. Me arrepiento is the only form.
Verbs with a meaning shift between reflexive and non-reflexive
Some pairs go beyond aspect or change-of-state — the meaning genuinely splits.
| Bare verb | Reflexive | Meaning difference |
|---|---|---|
| acordar (to agree) | acordarse de (to remember) | completely different meanings |
| despedir (to fire/dismiss) | despedirse de (to say goodbye to) | different actions |
| negar (to deny) | negarse a (to refuse) | passive deny vs active refusal |
| ocurrir (to happen) | ocurrírsele a uno (to occur to someone, have an idea) | event vs mental flash |
| fijar (to fix/fasten) | fijarse en (to notice / pay attention) | physical vs perceptual |
| parecer (to seem) | parecerse a (to resemble) | opinion vs likeness |
| ir (to go) | irse (to leave) | direction vs departure (covered above) |
Acordamos vernos el viernes a las ocho.
We agreed to meet on Friday at eight.
¿Te acuerdas de aquella noche en Granada?
Do you remember that night in Granada?
Despidieron a tres empleados ayer.
They fired three employees yesterday.

The lexical shift in these pairs is not predictable — learn each pair as two separate vocabulary items. The lists are finite and the high-frequency pairs are few.
Required, optional, wrong: a decision chart
For any verb pair, the se falls into one of three categories.
Se is required (won't make sense without it)
- Inherently reflexive verbs (arrepentirse, atreverse, quejarse, suicidarse, desmayarse).
- Some change-of-state verbs when the action is genuinely the change of state, not the activity (me dormí a las once — dormí would shift meaning to I slept).
- True reflexive meaning (me lavé el pelo — without me, you washed someone else's hair).
Se is optional (changes the flavour, not the grammar)
- Aspectual se with a bounded object (comí una manzana and me comí una manzana are both grammatical; the reflexive adds emphasis on completion).
- Ir vs irse when the departure focus is implied by context.
Se is wrong
- With mass nouns or generic activities (bebo agua, como pan, leo libros — adding me sounds odd).
- On verbs that don't have an attested reflexive form (ser, estar, haber, existir, parecer in the seems sense — no me ser, me estar).
- When the subject can't logically act on itself or change state in the way the reflexive implies.
❌ Me como pan todos los días.
Aspectual se needs a bounded object — pan as mass noun blocks it.
✅ Como pan todos los días. / Me he comido medio bocadillo.
I eat bread every day. / I've polished off half a sandwich.
Don't overapply the reflexive
English speakers, having learned that Spanish is "full of reflexives", sometimes apply se to verbs that don't take it. The reflexive isn't free — it adds specific meaning, and most plain transitive verbs don't need it.
❌ Me trabajo ocho horas al día.
Trabajar is not reflexive — no completion, no change of state, no inherent reflexivity.
✅ Trabajo ocho horas al día.
I work eight hours a day.
For more on these errors see errors/reflexive-overuse.
Common Mistakes
❌ Voy a casa, hasta mañana.
When taking leave, Spanish marks the departure with irse, not the directional ir.
✅ Me voy a casa, hasta mañana.
I'm off home, see you tomorrow. — me voy for the departure focus.
❌ Anoche dormí a las once mientras leía.
Falling asleep is a change of state — dormirse, not dormir.
✅ Anoche me dormí a las once mientras leía.
Last night I fell asleep at eleven while reading. — me dormí marks the transition.
❌ Arrepiento de haberle mentido.
Arrepentirse is inherently reflexive — no bare form.
✅ Me arrepiento de haberle mentido.
I regret having lied to him. — me arrepiento, the only valid form.
❌ Acuerdas de mi número, ¿verdad?
The remembering sense requires acordarse de. Acordar without se means to agree.
✅ Te acuerdas de mi número, ¿verdad?
You remember my number, right? — te acuerdas, the reflexive for memory.
❌ Convertí en programador después de la pandemia.
The becoming sense requires convertirse en — the bare convertir means to physically convert something.
✅ Me convertí en programador después de la pandemia.
I became a programmer after the pandemic. — me convertí en, change-of-identity.
❌ Me bebo agua todos los días.
Aspectual se needs a bounded object; agua alone is mass.
✅ Bebo agua todos los días. / Me bebo dos vasos de agua al día.
I drink water every day. / I drink two glasses of water a day.
❌ El niño cayó en el parque y empezó a llorar.
An accidental fall takes caerse, not caer (which is more for objects or directional falling).
✅ El niño se cayó en el parque y empezó a llorar.
The kid fell over in the park and started crying. — caerse for the accident.
Key Takeaways
- The Spanish reflexive does three jobs: true reflexive (subject acts on itself), reciprocal (each other), and pronominal/aspectual/change-of-state (the se is part of the lexical verb). The third has no English morphological match.
- Aspectual se marks completion with verbs of consumption and a bounded object: me comí una manzana entera. Won't work with mass nouns or unbounded quantities.
- Change-of-state se marks the moment of entering a state: dormirse (fall asleep), irse (leave), quedarse (stay), caerse (fall over), encontrarse (feel/be located), verse (meet up).
- Spanish has no single verb for to become. Use ponerse (temporary state), volverse (sudden/unwilled change), hacerse (gradual / through effort), quedarse (result of an event), or convertirse en (transformation into a noun).
- Inherently reflexive verbs cannot drop the pronoun: me arrepiento, te atreves, se queja, nos esforzamos.
- Some pairs split lexically: acordar (agree) / acordarse de (remember), despedir (fire) / despedirse de (say goodbye), negar (deny) / negarse a (refuse), parecer (seem) / parecerse a (resemble), fijar (fix) / fijarse en (notice).
- Don't overapply the reflexive: plain transitive verbs (trabajar, leer, escribir, comprar) don't take se in their everyday meanings.
- Three categories per verb: required (inherent or change-of-state), optional (aspectual emphasis), or wrong (no licit reflexive in that meaning).
For pronoun placement and conjugation see pronouns/reflexive-verbs; for meaning-shift pairs pronouns/reflexive-meaning-change; for the inherently-reflexive list pronouns/inherently-reflexive; for the se of becoming verbs/classes/become-verbs.
