Forgetting the Feminine Form

Confusing Complexity and Difficulty
Mistake: “Using 'difícil' when you really mean 'complejo'.”
Correction: 'Difícil' just means 'hard to do'. 'Complejo' means 'made of many parts'. While complex things are often difficult, use 'complejo' when you want to emphasize the structure.
