💡 Grammar Points
Gender Invariance
Unlike many Spanish adjectives, 'débil' is the same for both masculine and feminine nouns: 'el hombre débil' and 'la mujer débil'.
Making it Plural
To make 'débil' plural, you must add '-es': 'débiles' (e.g., 'los músculos débiles').
Ser vs. Estar
Use 'ser' (es) for permanent weakness (a characteristic), and 'estar' (está) for temporary weakness (after sickness or exercise).
❌ Common Pitfalls
Forgetting the Accent
Mistake: "debil (without accent)"
Correction: The stress in Spanish usually falls on the second-to-last syllable, but 'débil' is an exception. The accent mark is necessary to indicate the stress falls on the first syllable: DÉ-bil.

Frequently Asked Questions
Why does 'débil' have an accent mark?
'Débil' naturally stresses the first syllable (DÉ-bil). Since it ends in 'L' (a consonant other than N or S), Spanish rules say the stress should fall on the last syllable. The written accent mark is necessary to override this standard rule and keep the stress on the first syllable.
Can 'débil' ever mean 'stupid' or 'slow'?
While the related French cognate 'débile' often means 'stupid' or 'slow,' in modern Spanish, 'débil' almost exclusively means 'weak' or 'frail.' You should use words like 'tonto' or 'estúpido' if you mean stupid.
