In what context do you pronounce 行く as ゆく?


I am not entirely sure in what context you pronounce 行く as ゆく. I've read that
it is pronounced as ゆく in more formal situations and in songs. For example, in
the song lyric 闇へと進み行く it is pronounced as ゆく. Is this correct? Is it only
pronounced as ゆく in songs and formal situations? Surely there must be
something deeper to it than that.




Yo User13701, you use ゆく instead of いく when you:

  * want to show off.
  * write a song.
  * write a poem.
  * say the train/bus/plan etc direction.
