Frequently Asked Questions
Do other verbs of opinion like 'pensar' (to think) follow the same rule?
Yes, they do! 'Pensar' (to think), 'suponer' (to suppose), and 'parecer' (to seem) all work just like 'creer'. When they are positive, you use the indicative. When they are negative ('no pienso que', 'no supongo que'), you use the subjunctive to express doubt.
What happens if I use the wrong mood? Will people still understand me?
Yes, people will almost certainly understand you, but it will sound incorrect to a native speaker. Using the wrong mood can sometimes subtly change the meaning from 'I doubt it' to 'I am stating a fact', so mastering this distinction is key to sounding more natural and precise.
