Common mistakes with regularizar
The errors learners actually make with regularizar, each with the wrong form, the right form, and why it is wrong.
Mistake 1: Adding a reflexive pronoun that does not belong
- Wrong: Yo me regularizo su situación en el país.
- Right: Yo regularizo su situación en el país.
- Why: regularizar is not reflexive, so there is no pronoun to add. Yo regularizo su situación en el país. is the correct sentence, and the extra pronoun changes the meaning.
Mistake 2: Using the present tense after espero que
- Wrong: Espero que él regulariza los papeles de la empresa.
- Right: Espero que él regularice los papeles de la empresa.
- Why: After espero que Spanish needs the subjunctive, and for regularizar the subjunctive also changes z to c: regularice, not regulariza.
Mistake 3: Using the present tense for yesterday
- Wrong: Ayer, yo regularizo los papeles de la empresa.
- Right: Ayer, yo regularicé los papeles de la empresa.
- Why: Ayer means yesterday, so the action is finished and needs the preterite. The present tense is for habits and routines, not for yesterday: Ayer, yo regularicé los papeles de la empresa. — "Yesterday, I regularised the company's papers."
Mistake 4: Mixing up the gerund and the participle
- Wrong: Estoy regularizado la matrícula del coche.
- Right: Estoy regularizando la matrícula del coche.
- Why: After estar you need the gerund regularizando for the progressive. The participle regularizado goes with haber in the perfect tenses (he regularizado), never after estar.
Mistake 5: Using the él form for nosotros
- Wrong: Nosotros regulariza su situación en el país.
- Right: Nosotros regularizamos su situación en el país.
- Why: The person and the ending must match: nosotros takes regularizamos, while regulariza belongs to él and ella. Check the person first, then choose the form.

Frequently asked questions about regularizar
Is regularizar regular?
Almost. regularizar is a spelling-changing (z → c before e) -ar verb, so its endings are regular but its spelling changes in some forms: Watch the spelling: the z becomes c before e, so the yo preterite is regularicé and the subjunctive forms start with c, for example regularice. The rest of the conjugation follows the regular pattern, and the tables above show every form exactly.
What does regularizar mean, and when do I use it?
regularizar means "to regularise" in English. Use it when you talk about his situation in the country, the company's papers, the car's registration and the payment of the taxes — for example: Yo regularizo su situación en el país. — "I regularise his situation in the country." It is a practical verb for everyday conversation, and it appears in all the tenses on this page.
How do you say it in a real sentence?
A natural sentence is: Yo regularizo su situación en el país. — "I regularise his situation in the country." Change the person using the table above, and change the complement to talk about your own life: the verb stays the same, only the ending changes.
Is there a reflexive form of regularizar?
No. regularizar is not reflexive, so it is used without a pronoun: Yo regularizo su situación en el país. — "I regularise his situation in the country." Adding me, te or se would change the meaning, so keep the verb plain unless you mean the reflexive partner.
When do I use the present tense instead of the preterite with regularizar?
Use the present for habits and routines: Yo regularizo su situación en el país. — "I regularise his situation in the country." Use the preterite for one finished action: Ayer, yo regularicé su situación en el país. — "Yesterday, I regularised his situation in the country." If the action happens regularly, choose the present; if it happened once and is finished, choose the preterite.
