The Gaelic title (pronounced approximately like »shorn troos
WILLI-shan«) means »William's Old Trousers«, which has a little less
of a Celtic ring to it.

The spelling of Truibhas/Triubhas has been inconsistent for many years.  In this database the entry is now spelled »Triubhas«, with the »Truibhas« spelling as an official alias. The reasoning for this is that the »Truibhas« version in the 1974 edition of Book 27 was apparently a typo.

Asked about the spelling in November 2011 the RSCDS (Elspeth Gray) replied:

To this statement from Elspeth, Anselm adds:  »Note, though, that *Highland Dancing*, the official textbook of the SOBHD, spells the highland dance ›Triubhas‹, and has done so since the first edition of 1955.«
