💡 Grammar Points
Masculine Noun Rule
Since 'castigo' ends in -o, it is a masculine noun. Always use the masculine articles (el, un, los, unos) with it.
⭐ Usage Tips
Formal vs. Informal
While 'castigo' is neutral, in formal legal contexts, 'pena' (penalty/sentence) or 'sanción' (sanction) might be preferred over 'castigo'.

The stern gesture of the figure imposing a consequence visualizes the first-person verb form, "castigo" (I punish).
castigo(verb)
I punish
?first-person singular present tense
I chastise
?formal synonym
📝 In Action
Yo castigo el mal comportamiento de mis hijos.
A1I punish the bad behavior of my children.
Si miento, sé que castigo mi conciencia.
B2If I lie, I know I punish my conscience (I feel guilty).
💡 Grammar Points
Spelling Change for Sound
To keep the hard 'g' sound (like in 'go') before the vowels 'e' and 'i', the letter 'g' must change to 'gu'. This happens in the preterite ('yo castigué') and throughout the present subjunctive ('que yo castigue').
❌ Common Pitfalls
Missing the 'u'
Mistake: "Yo castigé (in the preterite)"
Correction: Yo castigué. If you don't add the 'u', the 'g' would sound like the 'h' in 'hello' in Spanish.
