This is definitely a bit of a stupid question… but methinks this happens to a good number of immigrants. Asking because there is a bit of a funny philosophical debate here:
- Technically the second language is not “native” by virtue of you not growing up with it
- But you speak it better than your native language, so skill-wise it is “native”
So do you have “native” language skills, or would you consider yourself simply highly “fluent” at the second language?
It depends on whether you treat the answer as “like a native” or “I am a native”. The word native is etymologically rooted in “born into it”.
To sum up: You can speak a second language better than a native and have a proficiency of a native speaker without being a native speaker of the language.
