How to Say "to heighten" in Spanish

Spelling Change Alert
In the past tense (Preterite) 'yo' form and all 'wish/command' forms (Subjunctive), the 'c' changes to 'qu' to keep the hard 'K' sound. For example: 'yo intensifiqué' instead of 'intensificé'.
Using 'se' with Intensificar
When an action becomes more intense on its own (like a storm or a smell), we often add 'se' at the end: 'El olor se intensifica' (The smell is getting stronger).
The 'C' to 'QU' spelling error
Mistake: “Yo intensificé mis estudios.”
Correction: Yo intensifiqué mis estudios. You need the 'qu' because a 'c' followed by an 'e' makes a soft 'S' sound in Spanish, and we want to keep the 'K' sound from the original word.
