Hakan etymology

[ancalimon]

I'm trying to find out about this word.

I guess it's related to Han - Khan - An

But what does the Hak-Ha- Haq sound in front of Han mean?

the etymology dictionary I have simply shows that it entered Farsi and Arabic from Turkic but nothing else.

Do you think it could be related to masculinity, justice and equity?

It's cognate to Khağan (which became khaan).

[H. İhsan Erkoç]

Khāqān is just the Arabo-Persian version of the Turkic title Qaghan.

[Ardavarz]

I have met a similar word from Indo-Scythian (Saka) inscriptions mentioned by J. Harmatta. It was hagāna if I remember correctly (unfortunately I don't own this book, I just saw it Google Books). He derives it from Iranian *fra-ka-ana - "leader" which not seems very plausible to me.

Also a folk etymology of Volga Bulgars maintains that this is an onomatopoetic word for thunder or "voice of God" metaphorically designating the shaman or the king and thus - the "sacred ruler".
