Crecer — "to grow" — is the textbook member of a family of -cer and -cir verbs that share one tiny but reliable irregularity: when a -cer verb is preceded by a vowel (here, the e of cre-), the yo form of the present indicative inserts a z before the c, giving crezco instead of creco. That same zc spreads through the whole present subjunctive (crezca, crezcas, crezca…) and through the usted/ustedes/nosotros imperatives. Everywhere else, crecer is a perfectly regular -er verb. Once you internalize crezco / crezca, you have the same template for conocer, parecer, ofrecer, merecer, agradecer, aparecer, desaparecer, obedecer, nacer, pertenecer, padecer, establecer, traducir, conducir, producir, and many more.
Non-finite forms
| Form | Spanish | English |
|---|---|---|
| Infinitivo | crecer | to grow |
| Infinitivo compuesto | haber crecido | to have grown |
| Gerundio | creciendo | growing |
| Gerundio compuesto | habiendo crecido | having grown |
| Participio | crecido (regular) | grown |
The gerundio and participle are both fully regular. The zc spelling shift only happens when the ending starts with a or o — never before i or e, where the c alone already sounds soft.
Indicative — simple tenses
Presente — c>zc only in the yo form
| yo | tú | él/ella/usted | nosotros | vosotros | ellos/ellas/ustedes |
|---|---|---|---|---|---|
| crezco | creces | crece | crecemos | crecéis | crecen |
Only the yo form is irregular — every other slot is standard -er. The z slips in because the o ending would otherwise force the c to sound hard (like co in casco). The z preserves the soft sound while leaving the spelling unambiguous.
Crezco más rápido cuando me cuidan, ya lo sé, pero me da pereza.
I grow faster when I take care of myself, I know, but I can't be bothered. (figurative, about personal growth)
Mis sobrinas crecen tan rápido que ya casi no las reconozco.
My nieces are growing so fast I barely recognise them anymore.
El paro crece mes a mes en esta zona del país.
Unemployment is growing month by month in this part of the country.
Pretérito perfecto simple — fully regular
The preterite is completely standard -er. No spelling shift, because the endings start with i.
| yo | tú | él | nosotros | vosotros | ellos |
|---|---|---|---|---|---|
| crecí | creciste | creció | crecimos | crecisteis | crecieron |
Crecí en un pueblo de la sierra de Madrid, rodeado de pinos.
I grew up in a village in the Madrid mountains, surrounded by pine trees.

Pretérito imperfecto — fully regular
| yo | tú | él | nosotros | vosotros | ellos |
|---|---|---|---|---|---|
| crecía | crecías | crecía | crecíamos | crecíais | crecían |
The imperfect is the natural tense for "growing up" as a setting — childhood landscapes, ongoing processes.
Mientras yo crecía aquí, mis primos crecían en Galicia bajo la lluvia.
While I was growing up here, my cousins were growing up in Galicia in the rain.
Futuro simple — fully regular
| yo | tú | él | nosotros | vosotros | ellos |
|---|---|---|---|---|---|
| creceré | crecerás | crecerá | creceremos | creceréis | crecerán |

Condicional — fully regular

|---|---|---|---|---|---|

Indicative — compound tenses
All compound tenses use haber with the regular participle crecido.
Pretérito perfecto compuesto
| yo | tú | él | nosotros | vosotros | ellos |
|---|---|---|---|---|---|
| he crecido | has crecido | ha crecido | hemos crecido | habéis crecido | han crecido |

Habríamos crecido juntos si no nos hubiéramos mudado.
We would have grown up together if we hadn't moved away.
Subjunctive — simple tenses
Presente de subjuntivo — zc everywhere
This is where the zc really earns its keep. Because the present subjunctive of -er verbs uses -a endings, the zc shows up in every form — not just the yo, as in the indicative.
| yo | tú | él | nosotros | vosotros | ellos |
|---|---|---|---|---|---|
| crezca | crezcas | crezca | crezcamos | crezcáis | crezcan |
Quiero que mis hijos crezcan en un sitio tranquilo, no en una gran ciudad.
I want my children to grow up somewhere quiet, not in a big city.
Es muy probable que la inflación crezca otra vez en otoño.
It's very likely that inflation will rise again in autumn.
Imperfecto de subjuntivo (-ra / -se) — fully regular
Built from the 3rd-plural preterite stem (crecieron → crecie-), which has no zc. The imperfect subjunctive is therefore completely standard.
| yo | tú | él | nosotros | vosotros | ellos | |
|---|---|---|---|---|---|---|
| -ra | creciera | crecieras | creciera | creciéramos | crecierais | crecieran |
| -se | creciese | crecieses | creciese | creciésemos | crecieseis | creciesen |
The -ra set is the conversational default in Spain; the -se set is mostly literary.
Si el negocio creciera al ritmo que esperábamos, contrataríamos a tres personas más.
If the business were growing at the rate we expected, we'd hire three more people.
Subjunctive — compound tenses
Pretérito perfecto de subjuntivo
| yo | tú | él | nosotros | vosotros | ellos |
|---|---|---|---|---|---|
| haya crecido | hayas crecido | haya crecido | hayamos crecido | hayáis crecido | hayan crecido |
Me alegra que hayas crecido tanto como persona en este último año.
I'm glad you've grown so much as a person over this past year.
Pluscuamperfecto de subjuntivo
| yo | tú | él | nosotros | vosotros | ellos | |
|---|---|---|---|---|---|---|
| -ra | hubiera crecido | hubieras crecido | hubiera crecido | hubiéramos crecido | hubierais crecido | hubieran crecido |
| -se | hubiese crecido | hubieses crecido | hubiese crecido | hubiésemos crecido | hubieseis crecido | hubiesen crecido |
Si la empresa hubiera crecido más rápido, ahora estaríamos cotizando en bolsa.
If the company had grown faster, we'd now be listed on the stock exchange.
Imperative
The imperative inherits the zc from the subjunctive — except in the tú affirmative (which uses the bare 3rd-singular indicative crece) and the vosotros affirmative (which uses creced, the infinitive minus -r plus -d).
| Form | Affirmative | Negative |
|---|---|---|
| tú | crece | no crezcas |
| usted | crezca | no crezca |
| nosotros | crezcamos | no crezcamos |
| vosotros | creced | no crezcáis |
| ustedes | crezcan | no crezcan |
Imperatives of crecer are rare in real conversation because you don't normally order something to grow. They show up mostly in metaphorical contexts: crece como persona ("grow as a person"), que crezca el negocio ("may the business thrive").
Crece, niño, crece, que aún te queda mucho.
Grow, child, grow — you've still got a long way to go. (affectionate)
¡Que crezca la empresa, brindemos por ello!
May the company grow — let's drink to that!
Other -cer / -cir verbs that work the same way
Every verb below takes zc in the same slots as crecer: the yo present, the entire present subjunctive, and the imperatives derived from the subjunctive.
| Verb | Meaning | 1st person present |
|---|---|---|
| conocer | to know (people, places) | conozco |
| parecer | to seem, to look like | parezco |
| ofrecer | to offer | ofrezco |
| merecer | to deserve | merezco |
| agradecer | to thank, to be grateful for | agradezco |
| aparecer | to appear | aparezco |
| desaparecer | to disappear | desaparezco |
| obedecer | to obey | obedezco |
| nacer | to be born | nazco |
| pertenecer | to belong | pertenezco |
| traducir | to translate (also irregular preterite) | traduzco |
| conducir | to drive (also irregular preterite) | conduzco |
Note that traducir, conducir, producir and their -ducir siblings share the zc in the present but additionally have an irregular preterite stem (traduje, conduje, produje) — those are extra irregularities beyond the crecer template.

The classic English-speaker error
English grow is both intransitive ("the plant grows") and transitive ("she grows tomatoes"). Spanish crecer is almost exclusively intransitive — things grow by themselves. When a person cultivates something, you reach for cultivar (plants, crops) or criar (animals, children).
- to grow tomatoes → cultivar tomates
- to grow chickens / cattle → criar gallinas / ganado
- to grow a beard / hair → dejarse crecer la barba / el pelo (pronominal + crecer)
- to grow children (raise) → criar hijos
Saying crezco tomates is grammatically deformed and will sound like you yourself are turning into a tomato. Use cultivo.
✅ Cultivamos nuestros propios tomates en el huerto.
We grow our own tomatoes in the vegetable garden.
❌ Crecemos nuestros propios tomates en el huerto.
Wrong — *crecer* is intransitive. Use *cultivar* for growing crops.
✅ Mis abuelos criaron cerdos durante años.
My grandparents raised pigs for years.
Common Mistakes
❌ Yo creco mucho cada verano.
The yo form needs the *z* — it's *crezco*, not *creco*.
✅ Yo crezco mucho cada verano.
I grow a lot every summer.
❌ Quiero que mis hijos crecan sanos.
The present subjunctive needs *zc* throughout — *crezcan*, not *crecan*.
✅ Quiero que mis hijos crezcan sanos.
I want my children to grow up healthy.
❌ En la finca crecemos manzanos.
*Crecer* is intransitive — for cultivating, use *cultivar*: *cultivamos manzanos*.
✅ En la finca cultivamos manzanos.
On the farm we grow apple trees.
❌ La economía crezció el año pasado.
The preterite is fully regular — *creció*, not *crezció*. The *zc* only appears before *a / o* endings.
✅ La economía creció el año pasado.
The economy grew last year.
Key Takeaways
- Crecer is the model c>zc verb: the z slips in before any a or o ending.
- The zc appears in only one slot of the indicative present: the yo form (crezco). Everything else (creces, crece, crecemos, crecéis, crecen) is standard.
- The zc appears in every slot of the present subjunctive: crezca, crezcas, crezca, crezcamos, crezcáis, crezcan.
- The preterite, imperfect, future, conditional, gerundio, and participle are all fully regular — no zc before i or e endings.
- The same template covers conocer, parecer, ofrecer, merecer, agradecer, aparecer, obedecer, nacer, pertenecer and the entire -ducir family (conducir, traducir, producir).
- Crecer is intransitive in Spanish — for "growing" plants, use cultivar; for "growing" children or animals, use criar; for hair / beard, use dejarse crecer.
- The reflexive idiom crecerse (to rise to a challenge) is a peninsular gem worth knowing.
