One Form for All
In Spanish, most adjectives ending in 'e' don't change for men or women. Whether you are talking about 'un hombre' or 'una mujer', the word stays 'invencible'.
Using 'Ser' vs 'Sentirse'
Use 'ser' to describe a permanent quality ('The army is invincible') and 'sentirse' to describe how someone feels inside ('I feel invincible').
Don't add an 'a'!
Mistake: “La mujer invencibla.”
Correction: La mujer invencible. Adjectives ending in -e do not change to -a for feminine things.
Confusing with 'invisible'
Mistake: “No puedo ver el fantasma, es invencible.”
Correction: No puedo ver el fantasma, es invisible. 'Invencible' means you can't be defeated, while 'invisible' means you can't be seen.
