At the B1 level of Spanish, it becomes essential to express doubts, uncertainty, or hesitation in conversations. Whether you’re discussing plans, offering opinions, or considering possibilities, having the right phrases to express uncertainty will improve your fluency. In this article, we will explore useful phrases, structures, and examples for expressing doubts and uncertainty in Spanish.

1. Common Phrases for Expressing Doubts

Here are some phrases frequently used to express doubt or uncertainty:

  • No estoy seguro/a de que… – I’m not sure that…
  • No sé si… – I don’t know if…
  • Dudo que… – I doubt that…
  • No creo que… – I don’t think that…
  • Es posible que… – It’s possible that…
Example Sentences:
  • No estoy seguro de que lleguemos a tiempo. (I’m not sure that we’ll arrive on time.)
  • Dudo que ella venga a la fiesta. (I doubt that she’ll come to the party.)
  • Es posible que llueva esta tarde. (It’s possible that it will rain this afternoon.)

2. Using the Subjunctive for Uncertainty

In Spanish, the subjunctive mood is often used to express doubt, uncertainty, or conditions that are not yet certain. The subjunctive is triggered by verbs of doubt, such as dudar (to doubt), and expressions like no creo que (I don’t think that).

Conjugation of the Subjunctive:
  • -ar verbshablar (to speak)
    • Yo hable
    • Tú hables
    • Él/Ella/Usted hable
    • Nosotros hablemos
    • Vosotros habléis
    • Ellos/Ellas/Ustedes hablen
  • -er/ir verbscomer (to eat), vivir (to live)
    • Yo coma / viva
    • Tú comas / vivas
    • Él/Ella/Usted coma / viva
    • Nosotros comamos / vivamos
    • Vosotros comáis / viváis
    • Ellos/Ellas/Ustedes coman / vivan
Example Sentences:
  • No creo que el tren llegue a tiempo. (I don’t think the train will arrive on time.)
  • Dudo que podamos terminar el proyecto hoy. (I doubt that we can finish the project today.)

3. Expressions of Probability

To express possibilities or likelihood, you can use phrases such as:

  • Es probable que… – It’s probable that…
  • Puede ser que… – It could be that…
  • Tal vez… – Maybe…
  • Quizás… – Perhaps…
Example Sentences:
  • Es probable que vayamos al cine este fin de semana. (It’s probable that we’ll go to the cinema this weekend.)
  • Quizás llueva mañana. (Perhaps it will rain tomorrow.)
  • Puede ser que ella esté en casa. (It could be that she is at home.)

4. Using “A lo mejor”

Another way to express doubt is by using the phrase a lo mejor, which means “maybe” or “perhaps.” Unlike other expressions of doubt, a lo mejor is followed by the indicative, not the subjunctive.

Example Sentences:
  • A lo mejor no llego a tiempo. (Maybe I won’t arrive on time.)
  • A lo mejor vamos de vacaciones en agosto. (Maybe we’ll go on vacation in August.)

5. Expressing Hesitation

In addition to doubt, expressing hesitation is an important skill in conversation. Use phrases like these to show uncertainty or hesitation:

  • No sé si… – I don’t know if…
  • Estoy dudando… – I’m hesitating…
  • Todavía no estoy seguro/a… – I’m still not sure…
Example Sentences:
  • No sé si debo aceptar el trabajo. (I don’t know if I should accept the job.)
  • Estoy dudando si ir o no. (I’m hesitating about whether to go or not.)

6. Practice Tips

A. Practice with Scenarios

Create hypothetical scenarios where you might need to express doubt or uncertainty, such as deciding between two options or making travel plans.

B. Listen for Subjunctive

Listen to Spanish-language podcasts, news, or conversations to hear how native speakers express uncertainty using the subjunctive.

C. Engage in Conversations

Practice expressing doubts and uncertainty with a language partner, especially when discussing future plans or possibilities.
