Subjunctive Usage 2

What This Level Focuses On

This level expands subjunctive usage to situations involving:

• doubt
• negation
• uncertainty

Core Idea

The subjunctive is used when the speaker is not sure if something is true.

1. Doubt (Duda)

Used with verbs expressing doubt:

• dudar que
• no creer que
• no pensar que

Examples:

• Dudo que venga. = I doubt that he/she comes
• No creo que tengan razón. = I don’t think they are right

2. Negation (Negación)

When a statement is negated, it often triggers subjunctive.

• No es verdad que funcione. = It is not true that it works
• No pienso que sea correcto. = I don’t think it is correct

3. Uncertainty (Incertidumbre)

Used with expressions of possibility:

• es posible que
• es probable que
• puede que

Examples:

• Es posible que llueva. = It is possible that it rains
• Puede que llegue tarde. = He/She might arrive late

4. Contrast with Certainty

If the speaker is certain, use indicative:

• Creo que viene. ✔

If uncertain, use subjunctive:

• No creo que venga. ✔
