Thought verbs also mark stance
Spanish verbs of thinking do more than report mental activity. They show how strongly the speaker presents a claim, whether the speaker is reasoning, believing, judging, or offering an opinion, and whether the statement is asserted or withheld.
Compare:
Creo que es verdad.
I think/believe it is true.
No creo que sea verdad.
I don’t think it is true.
Pienso en mi familia.
I think about my family.
Considero importante revisar los datos.
I consider it important to review the data.
The key principle is:
Pensar, creer, opinar, and considerar differ in meaning, register, complement structure, and mood behavior.
Learners need both the vocabulary and the syntax.
Creer que: belief and assertion
Creer que commonly introduces a belief or opinion presented as an assertion.
Creo que tienes razón.
I think you’re right.
Creemos que el plan funciona.
We believe the plan works.
Ella cree que no hay problema.
She thinks there is no problem.
In affirmative clauses, creer que usually takes the indicative because the speaker presents the content as believed/asserted.
Creo que viene.
I think he/she is coming.
With negation, Spanish often uses the subjunctive:
No creo que venga.
I don’t think he/she is coming.
The negated belief no longer asserts the subordinate proposition. The mood marks that shift.
But real usage can be nuanced. No creo que viene may appear in some colloquial or dialectal contexts with special effects, but standard learner production should use the subjunctive after no creo que when denying the proposition.
Pensar que and pensar en
Pensar has two major patterns.
Pensar que introduces a thought or opinion:
Pienso que es una buena idea.
I think it is a good idea.
Pensamos que el precio es justo.
We think the price is fair.
Like creer, affirmative pensar que generally takes indicative. Negative no pienso que often takes subjunctive when it denies the subordinate proposition:
No pienso que sea necesario.
I don’t think it is necessary.
Pensar en means think about:
Pienso en mi familia.
I think about my family.
Estoy pensando en cambiar de trabajo.
I’m thinking about changing jobs.
Learners must not confuse the two patterns:
pensar que + clause
think that...
pensar en + noun/infinitive
think about...
Opinar: giving an opinion
Opinar is more explicitly about opinion. It often appears in discussions, journalism, debate, and formal speech.
Opino que debemos esperar.
I am of the opinion that we should wait.
Los expertos opinan que la medida no es suficiente.
Experts believe/are of the opinion that the measure is not sufficient.
It can sound more formal or deliberative than creer in everyday conversation. In casual speech, creo que is often the default. Opino que can sound like a stated position.
A useful noun is opinión:
En mi opinión, es demasiado pronto.
In my opinion, it is too early.
Considerar: evaluation and classification
Considerar means to consider, regard, judge, or deem. It is more formal and evaluative.
Considero importante revisar los datos.
I consider it important to review the data.
Lo consideran un experto.
They consider him an expert.
La ley considera este acto una infracción.
The law considers this act a violation.
Common structures:
considerar algo + adjective/noun
consider something adjective/a noun
considerar que + clause
consider that...
considerar + infinitive/noun
consider doing/something
Considerar is frequent in academic, legal, institutional, and analytical prose.
Negation and mood
Thought verbs are a major source of indicative/subjunctive contrast.
Affirmative belief:
Creo que es cierto.
I believe it is true.
Negated belief:
No creo que sea cierto.
I don’t believe it is true.
Questioned belief may vary by whether the speaker expects assertion, asks about belief, or expresses doubt:
¿Crees que es cierto?
Do you think it is true?
¿No crees que sea mejor esperar?
Don’t you think it might be better to wait?
The rule is not “creer always takes indicative.” The rule is about assertion, denial, doubt, and stance.
Stance strength and politeness
Creo que can soften a statement:
Creo que hay un error.
I think there is an error.
This may be less blunt than:
Hay un error.
There is an error.
Me parece que can soften further:
Me parece que hay un error.
It seems to me that there is an error.
Considero que sounds more formal and authoritative:
Considero que la decisión fue correcta.
I consider the decision correct.
Choosing a thought verb is also choosing a social posture.
Common learner errors
The first error is using pensar en when the meaning is “think that.”
Pienso que tienes razón.
not: Pienso en que tienes razón in ordinary learner production.
The second error is forgetting the subjunctive after negated belief:
No creo que sea verdad.
not: No creo que es verdad in standard Spanish.
The third error is overusing opino que in casual contexts where creo que sounds more natural.
The fourth error is translating considerar as “think” everywhere. It often means evaluate, judge, regard, or classify.
Remediation notes: mood after stance verbs
Thought verbs are not only vocabulary. They create a stance toward the following proposition, and that stance often controls mood.
Affirmative belief normally takes the indicative because the speaker presents the content as believed or asserted:
Creo que tiene razón.
I think he/she is right.
Pienso que el plan funciona.
I think the plan works.
Negative belief often takes the subjunctive because the speaker does not assert the subordinate content:
No creo que tenga razón.
I don’t think he/she is right.
No pienso que el plan funcione.
I don’t think the plan works.
This is the productive learner rule. Real discourse can be subtler: questions, echoing, irony, contrast, and regional habits can affect mood. But for production, no creer que + subjunctive is a high-value default.
The second major repair is pensar que versus pensar en:
Pienso que es buena idea.
I think it is a good idea.
Pienso en mi familia.
I think about my family.
Spanish also uses pensar + infinitive for intention in many contexts:
Pienso viajar en julio.
I plan to travel in July.
This is not the same as pensar en viajar, which focuses on considering the idea of traveling.
Opinar is useful when giving a stated opinion, often in public, academic, journalistic, or deliberative contexts:
Opino que la propuesta es viable.
I am of the opinion that the proposal is viable.
Considerar can classify or evaluate:
Considero injusta la decisión.
I consider the decision unfair.
Considero importante revisar los datos.
I consider it important to review the data.
Considero que debemos esperar.
I believe/consider that we should wait.
Do not force all English “think” into pensar. Sometimes the Spanish sentence is about belief (creer), active thought (pensar), formal opinion (opinar), evaluation/classification (considerar), or appearance/stance softening (parecer). The verb you choose tells the reader how committed, formal, or evaluative your statement is.

Final rule
Thought verbs are stance tools.
Use creer que for belief, pensar que for thought/opinion, pensar en for thinking about, opinar que for explicit opinion, and considerar for evaluation or classification. Then let mood follow the speaker’s stance toward the subordinate clause.
