Off-topic: Referrer as a concept and word/term is correct, but as pointed out there was a typo when the RFCs were written which cemented it in the spec, and once servers and browsers started using the typoed version with a single R in their header implementations, it couldn't easily be changed, and it's stuck since then. And unlike modern "standards" that are being changed on a saturday whim all the time, the older Internet took them a lot more serious and as unchanging.
