USAGE:
()()し originally refers to the starting square in a board game (like sugoroku). The expression ()()しに(もど)る (to go back to square one) is extremely common and is the primary way this word is used in everyday Japanese.

COMMON COLLOCATIONS:

  • ()()しに(もど)る (to go back to square one)
  • ()()しから (from the beginning)
  • ()()しに(もど)す (to put something back to the starting point)

CULTURAL NOTE:
The word comes from すごろく (Japanese backgammon/board game), where ()()し is the starting square. Landing on certain squares sends you back to ()()し.
