Why not "سريع وجيّد"
The order of the adjectives has an importance?
I had the same question too.
The female جيدة is marked as a typo but should be wrong
The doctor was from Fast and Furious series i guess
Why not سريعة"؟"
Because the form you propose is feminine.
Why not “doktorun”?
If you want to pronounce the case endings, yes: bashiir-un duktuur-un jayyid-un wa-sarii3.
