Triumph Forks

The "Triumph Forks", which are often talked about by the Fishmen in The Wind Waker, are none other than the pieces of the Triforce of Courage. In the time of The Wind Waker, the word 'Triforce' had been all but forgotten, mostly due to the Great Flood which created the Great Sea of Hyrule. Over time, changes in the Hylian tounge led to the mistranslation of the word "Triforce" into "Triumph Forks".

This has been proved by the fact that the Talking Fish in TWW mentions Triumph Forks on different Islands, which later turn out to be locations of the Pieces of the Triforce of Courage. The Japanese name for this is Tarai to Hosu, whilst Triforce is Toraifosu. The Triumph Forks are mentioned again in The Minish Cap, appearing as titles of books in the Library (The titles appear as Modern Hylian. Translated it said Ta Ra I To Ho Su.) This suggests that The Minish Cap takes place after Ocarina of Time.

It is also possible that the Fishman calls them the Triumph Forks because the makers of the game might not want to spoil anything by mentioning the Triforce to a new player who fed a fish. It would spoil one of the goals in the game.
