One Word for Male and Female
The word 'detective' stays the same for men and women. You just change the little word before it to show who you're talking about: 'el detective' for a man and 'la detective' for a woman.
An Adjective That Stays the Same
When used to describe something, 'detective' doesn't change for gender. It's 'una película detective' (a detective movie) and 'un libro detective' (a detective book). It only changes for plural: 'novelas detectives'.
No 'Detectiva'
Mistake: “La detectiva encontró la pista.”
Correction: La detective encontró la pista. The word 'detective' doesn't change its ending for gender, even when talking about a woman.
Placement After the Noun
Mistake: “Una detective novela.”
Correction: Una novela detective. In Spanish, adjectives that describe a 'type' or 'category' of something usually go after the thing they're describing.
