💡 Grammar Points

Subjunctive Trigger

You must use mientas (the special form of the verb) after expressions that show doubt, denial, or emotion about the action, like dudar que (to doubt that) or no creer que (not to believe that).

Irregular Vowel Change

The infinitive is 'mentir' (with 'e'), but in this form, the 'e' changes to 'ie' (mientas). This is a common pattern for many Spanish verbs like preferir (to prefer) and sentir (to feel).

❌ Common Pitfalls

Confusing Subjunctive and Indicative

Mistake: "Using the indicative form: *No creo que mientes.*"

Correction: The correct form is *No creo que mientas.* When you express doubt or denial, Spanish requires this special verb form (the Subjunctive) where English usually doesn't.

⭐ Usage Tips

Remember the Base Verb

Always remember that mientas is the 'tú' form of the verb mentir (to lie). If you can conjugate mentir correctly, you can use mientas naturally.
