How to Say "to ground" in Spanish
The most common Spanish word for “to ground” is “castigar” — use 'castigar' when referring to the punishment of a child or teenager, meaning to restrict their privileges or freedom..
castigar
/kah-stee-gar//kastiˈɣaɾ/

Examples

My parents are going to ground me this weekend.

The judge decided to punish the guilty party with a fine.
Es importante no castigar a los niños físicamente.
It is important not to punish children physically.
Spelling Change Alert
In the 'yo' form of the past tense, the 'g' changes to 'gu' (castigué) to keep the hard 'g' sound. Without the 'u', it would sound like an 'h'.
The 'Personal A'
When you are punishing a specific person, you must use 'a' after the verb. Example: 'Castigaron a Juan'.
Spelling the Past Tense
Mistake: “Yo castigé.”
Correction: Yo castigué. In Spanish, 'ge' sounds like an 'h', so we need the 'u' to maintain the hard sound of the original verb.
fundamentar
/foon-dah-mehn-TAHR//funda-menˈtaɾ/

Examples

Using 'en' to show the base
Just like we say 'based on' in English, Spanish uses the word 'en' after fundamentar. For example: 'Fundamentar en la realidad' (To base on reality).
A regular -ar verb
Good news! This verb follows the normal pattern for verbs ending in -ar, like 'hablar' or 'cantar,' so you don't need to learn any weird spelling changes.
Confusing with 'Fundar'
Mistake: “Fundé mi opinión en el libro.”
Correction: Fundamenté mi opinión en el libro.

Using 'En'
When you want to say you are basing an idea 'on' something, always use the word 'en'. For example: 'Se funda en la verdad' (It is based on the truth).
Reflexive Use
You will often see this as 'fundarse' (to be based). It’s a very common way to describe theories or legal decisions in the passive voice.
Wrong Preposition
Mistake: “Fundo mi idea sobre la experiencia.”
Correction: Fundo mi idea en la experiencia. (Use 'en' instead of 'sobre' when talking about foundations for arguments.)
