How to Say "to impede" in Spanish
The most common Spanish word for “to impede” is “impedir” — use 'impedir' when you want to say that something or someone obstructs, hinders, or prevents an action or event from happening..
impedir
/im-peh-DEER//im.peˈðiɾ/

Examples

Las nuevas normas impiden el acceso a vehículos pesados.
The new rules block access to heavy vehicles.
Using 'que' and the Special Verb Form
When you use 'impedir' to prevent someone else from doing something, you usually follow it with 'que' and the special verb form (the subjunctive). Example: 'Impidieron que yo entrara.' (They prevented me from entering).
The 'e' to 'i' Change
In many present tense forms, the 'e' in the middle of the verb stem changes to an 'i'. Think of it as 'i-mpide' instead of 'e-mpede'. This change also happens in the present subjunctive.
Forgetting the Stem Change
Mistake: “Yo *empedo* (Incorrect present tense)”
Correction: Yo *impido* (Correct present tense). Remember the 'e' becomes 'i' when the stress falls on that syllable.
Using the Wrong Mood
Mistake: “Impidió que ellos *salieron*.”
Correction: Impidió que ellos *salieran*. (The action being prevented requires the special verb form, the subjunctive, after 'que'.)
arrestar
ah-rrehs-TAHR/a.resˈtaɾ/

Examples
Los médicos intentaron arrestar el avance de la enfermedad.
The doctors tried to halt the advance of the disease.

Formal Usage
