tyu-tyu

The first change which takes place is the insertion of the sound of y, making tyu-tyu; upon the same principle which makes certain Englishmen say gyarden, kyind, and skyey, for garden, kind, and sky. The next change is for ty to become tsh. This we find also in English, where picture or pictyoor is pronounced pictshur, etc. Let, however, the change proceed, and the initial sound of t be lost.

Thus the English word breast = susu, Kowrarega; tyu-tyu, Gudang, and the English outrigger float = sarima, Kowrarega; charima, Gudang, which of these two forms is the older? Probably the Gudang, or the form in ty. If so, the series of changes is remarkable, and by attending to it we may see how sounds previously non-existent may become evolved. Thus let the original form for breast be tutu.
