Common Mistakes
Mistake: Writing 'aislo' without the accent.
Correct: aíslo
Why: Without the accent, the 'ai' would be a single syllable. The accent is needed to stress the 'i' specifically.
Mistake: Adding an accent to the nosotros form: 'aislámos'.
Correct: aislamos
Why: The stress falls on the 'a' in 'aislamos', so no written accent is needed.
