Common Mistakes
Mistake: Using the present tense instead of the future.
Correct: Instead of 'Yo defino mañana...', use 'Yo definiré mañana...'.
Why: The present tense is for now or habitual actions; the future tense is specifically for what will happen later.
Mistake: Confusing future endings with conditional endings.
Correct: Future endings are -é, -ás, -á, etc. (e.g., 'definirá'), while conditional endings are -ía, -ías, -ía, etc. (e.g., 'definiría').
Why: These are distinct tenses with different meanings and endings.
