And that's the quandary faced by a lot of gifted kids. Some choose to dumb down their language to fit in better and draw less attention to themselves... the chameleon effect.
And to complicate matters further, over-emphasizing comformity at that age may degrade vocabulary and complex language.
I went through a phase at around 13 where I was constantly matching what I intended to communicate to what was understood. Then I would play through scenes in my head at the end of the day to figure out if intent and outcome were matching. Then brainstorm different ways, methods to express things and try that next time.
One nice thing with that approach is it accidentally makes you question and analyze your intentions. When you realize you said something a certain way because you did intend the teacher to look dumb and you to look cool, then you have to own up at least to yourself.
