Common mistakes with sintetizar
The errors learners actually make with sintetizar, 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 sintetizo la información en un resumen.
- Right: Yo sintetizo la información en un resumen.
- Why: sintetizar is not reflexive, so there is no pronoun to add. Yo sintetizo la información en un resumen. is the correct sentence, and the extra pronoun changes the meaning.
Mistake 2: Using the present tense after espero que
- Wrong: Espero que él sintetiza los datos en un gráfico.
- Right: Espero que él sintetice los datos en un gráfico.
- Why: After espero que Spanish needs the subjunctive, and for sintetizar the subjunctive also changes z to c: sintetice, not sintetiza.
Mistake 3: Using the present tense for yesterday
- Wrong: Ayer, yo sintetizo los datos en un gráfico.
- Right: Ayer, yo sinteticé los datos en un gráfico.
- 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 sinteticé los datos en un gráfico. — "Yesterday, I synthesised the data into a chart."
Mistake 4: Mixing up the gerund and the participle
- Wrong: Estoy sintetizado la lección en tres ideas.
- Right: Estoy sintetizando la lección en tres ideas.
- Why: After estar you need the gerund sintetizando for the progressive. The participle sintetizado goes with haber in the perfect tenses (he sintetizado), never after estar.
Mistake 5: Using the él form for nosotros
- Wrong: Nosotros sintetiza la información en un resumen.
- Right: Nosotros sintetizamos la información en un resumen.
- Why: The person and the ending must match: nosotros takes sintetizamos, while sintetiza belongs to él and ella. Check the person first, then choose the form.

Frequently asked questions about sintetizar
Is sintetizar regular?
Almost. sintetizar 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 sinteticé and the subjunctive forms start with c, for example sintetice. The rest of the conjugation follows the regular pattern, and the tables above show every form exactly.
What does sintetizar mean, and when do I use it?
sintetizar means "to synthesise" in English. Use it when you talk about the information into a summary, the data into a chart, the lesson into three ideas and the compound in the laboratory — for example: Yo sintetizo la información en un resumen. — "I synthesise the information into a summary." 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 sintetizo la información en un resumen. — "I synthesise the information into a summary." 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 sintetizar?
No. sintetizar is not reflexive, so it is used without a pronoun: Yo sintetizo la información en un resumen. — "I synthesise the information into a summary." 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 sintetizar?
Use the present for habits and routines: Yo sintetizo la información en un resumen. — "I synthesise the information into a summary." Use the preterite for one finished action: Ayer, yo sinteticé la información en un resumen. — "Yesterday, I synthesised the information into a summary." If the action happens regularly, choose the present; if it happened once and is finished, choose the preterite.
