  • Common errors
Stating and backing up a view: Giving an opinion means doing two things: stating what you think («creo que…», «en mi opinión…») and justifying it with a reason («porque…», «ya que…»). A bare opinion with no reason stays in the lower bands; an opinion plus a reason plus an example is what the discursive writing and the oral conversation reward. One grammar point to watch: a negated opinion («no creo que…») switches the next verb into the subjunctive.
la opinión
opinion — what you personally think
creo que
I believe / think that — introduces an opinion (+ indicative)
justificar
to justify — to back up your opinion with a reason
estar de acuerdo
to agree — to share someone's view
el subjuntivo
the subjunctive — the verb mood triggered by «no creo que…»
el indicativo
the indicative — the ordinary verb mood after a plain «creo que…»
Opinion + reason, always: The single biggest mark-winner here is the justification. Never write «Creo que es bueno.» and stop — add «…porque…» or «…ya que…». In the oral, every opinion you give should be followed by a reason, ideally with an example.
Phrases for stating, agreeing, contrasting: Here is the phrase toolkit, grouped by job. Stating an opinion takes the indicative («creo que es…»). Agreeing / disagreeing lets you respond to others. And the trap: «no creo que / no pienso que» takes the subjunctive («no creo que sea…»).

Para dar una opinión (+ indicativo)

  • creo que… — I think that… («Creo que es importante.»)
  • pienso que… — I think that… («Pienso que tienes razón.»)
  • en mi opinión… — in my opinion… («En mi opinión, hace falta.»)
  • me parece que… — it seems to me that… («Me parece que funciona.»)
  • desde mi punto de vista… — from my point of view… («Desde mi punto de vista, es justo.»)

Para estar (o no) de acuerdo

  • estoy de acuerdo (con…) — I agree (with…)
  • no estoy de acuerdo — I disagree
  • por un lado… por otro lado… — on one hand… on the other hand…
Negated opinion → subjunctive: A plain opinion keeps the indicative: «Creo que es verdad.» But the moment you negate it, the verb after «que» becomes subjunctive: «No creo que sea verdad.» Same with «No pienso que…» → «No pienso que tenga razón.» This is the one form examiners look for here.

Where opinions earn marks: Opinion language is the backbone of the discursive writing and the oral conversation. Here are the moments you reach for it, each with a Spanish example — and notice that the reason («porque / ya que») is what turns a comment into an argument.

Cuándo expresar opinión

  • Discursive writing — «En mi opinión, deberíamos reciclar más, porque protege el medio ambiente.» (In my opinion, we should recycle more, because it protects the environment.)
  • The oral conversation — «Pienso que la tecnología ayuda, ya que facilita el estudio.» (I think technology helps, since it makes studying easier.)
  • Justifying with a reason — «Me parece útil porque ahorra tiempo.» (It seems useful to me because it saves time.)
  • Weighing two sides — «Por un lado es cómodo; por otro lado, es caro.» (On one hand it's convenient; on the other hand, it's expensive.)
  • Responding to someone — «Estoy de acuerdo, pero creo que falta información.» (I agree, but I think information is missing.)
Justify with «porque / ya que»: Whenever you state a view, attach a reason with «porque» or «ya que». An example after that («por ejemplo…») makes it stronger still. Opinion → reason → example is the chain that pushes you up the bands.
Opinion, reason, example, conclusion: Here is a short opinion paragraph built in the classic shape: opinion → reason → example → weighing both sides → mini-conclusion. Notice the plain opinions use the indicative («creo que reduce») while the negated one uses the subjunctive («no creo que sea»). Tap Ver traducción or 🔊 to hear it.

Una opinión en acción

Opinión, razón, ejemplo, conclusión

  1. En mi opinión, el transporte público es la mejor opción para la ciudad.
  2. Creo que reduce la contaminación, ya que hay menos coches en las calles.
  3. Por ejemplo, en mi ciudad el metro transporta a miles de personas cada día.
  4. Por un lado es barato; por otro lado, no llega a todos los barrios.
  5. Por eso, no creo que sea perfecto, pero pienso que es mejor que el coche.
Steal this skeleton: The chain is reusable for any topic: «En mi opinión… (opinion). Creo que… porque… (reason). Por ejemplo… (example). Por un lado… por otro lado… (two sides). Por eso, pienso que… (conclusion).» Drop in your topic and you have a full discursive paragraph.

The slips to watch for: Three classic opinion errors: forgetting the subjunctive after a negated opinion («no creo que es…» → «no creo que sea…»), giving an opinion with no justification, and English calques like translating I am agree word for word. Compare the right version with the typical mistake.

Correcto

  • No creo que sea buena idea.
  • Creo que es útil porque ahorra tiempo.
  • Estoy de acuerdo contigo.

Error común

  • No creo que es buena idea.
  • Creo que es útil.
  • Estoy de acuerdo. / Soy de acuerdo.
Negate → subjunctive, and always justify: Two checks before you move on: if your opinion is negated («no creo que…»), is the next verb in the subjunctive (sea, tenga, pueda)? And does every opinion have a reason attached? Also avoid the calque — it's «estoy de acuerdo», never «soy de acuerdo».
