voo-lneh-RAH-blehbulneˈɾable

Adjective Agreement (Number)
Since 'vulnerable' ends in '-e', it doesn't change based on whether the noun is masculine or feminine (es: 'la zona vulnerable', 'el grupo vulnerable'). However, you must add an '-s' for plural nouns: 'zonas vulnerables' or 'grupos vulnerables'.
Using the wrong verb
Mistake: “Estar vulnerable”
Correction: Ser vulnerable. Because vulnerability is usually a defining characteristic or a long-term state, you almost always use 'ser' (to be) instead of 'estar' (to be, temporary state). 'Ella es vulnerable' (She is vulnerable) is correct.
débiles
Examples
Las defensas del país son débiles contra un ataque sorpresa.
The country's defenses are weak against a surprise attack.
expuesto
eks-PWES-toheksˈpwesto

Matching the Noun
Since this acts as a descriptor, remember to change the ending to 'expuesta' for feminine things or 'expuestos/as' for plurals.
Choosing the right 'To Be'
Mistake: “Soy expuesto al sol.”
Correction: Estoy expuesto al sol.
frágil
Examples

Matching the Gender
Since this is an adjective, you must change the ending to match the person or thing you are describing. Use 'indefenso' for a male/masculine object and 'indefensa' for a female/feminine object.
Using 'Estar' vs 'Sentirse'
We usually use this word with 'estar' (to be) to describe a current state of lack of protection, or 'sentirse' (to feel) to describe the emotion of being vulnerable.
Don't confuse with 'Harmless'
