💡 Grammar Points

The 'GU' Spelling Change

When 'interrogar' is followed by an 'e' sound (like in the first-person past tense 'yo interrogue'), we add a 'u' after the 'g' to keep the hard 'g' sound, like in 'game'.

❌ Common Pitfalls

Interrogar vs. Preguntar

Mistake: "Using 'interrogar' for simple questions like 'What time is it?'"

Correction: Use 'preguntar' for everyday questions and 'interrogar' only for formal or serious questioning.

⭐ Usage Tips

Tone Matters

Using this word implies a position of authority. Don't use it with friends unless you are joking about acting like a detective!
