Is 翻す a former compound verb that merged into its current form?


The verb ひるがえす feels like it is made of two part ひる and かえす but I could not
find any references backing this interpretation. And I can't figure out what
would be ひる.

@snailboat also mentioned くつがえす whose meaning is very close to ひるがえす. If an
answer could solve both cases it would be much appreciated.




[翻]{ひるがえ}す is a transitive verb of [翻]{ひるがえ}る.  
It seems that it shows the movement of a flag originally.

This theory remains a matter of speculation.

> 翻る…[旗]{はた}が翻る(A flag flaps)  
>  →ひらひらと[裏]{うら}[返]{がえ}る→ひるがえる

others:

> [蘇]{よみがえ}る…[死者]{ししゃ}が蘇る(The dead revive)  
>  →[黄泉]{よみ}から[帰]{かえ}る→よみがえる

※黄泉 is the land of the dead.

I did not understand about [覆]{くつがえ}る...  
  
  
(about a hypothesis)  
This is an ancient Japanese poem([和歌]{わか})
