This is from the ICD 11:
Quote:
...and there is marked impairment in functional language (spoken or signed) relative to the individual’s age, with the individual not able to use more than single words or simple phrases for instrumental purposes, such as to express personal needs and desires.
I think if you can communicate with people in a relatively usual way, then I think you have functional language. It seem to really be about being able to use language to navigate your environment. It seems with your verbal intelligence, you are easily beyond that bar.
The interesting thing is they include sign language, which means you don't have to be verbal.
