💡 Grammar Points
The Z to C Swap
When you have a verb ending in -zar, the 'z' changes to a 'c' whenever it's followed by an 'e'. This happens in the 'yo' form of the past tense (rechacé) and all forms of the special 'wish' verb form (subjunctive).
❌ Common Pitfalls
Rechazar vs. Negar
Mistake: "Using 'negar' to decline an invitation."
Correction: Use 'rechazar'. 'Negar' means to claim something is not true (to deny), while 'rechazar' is to say no to something offered.
⭐ Usage Tips
