The change of mouth shape when vowels are pronounced determines which letter comes first and which letter comes last.
To distinguish ui-iu, such as vowel iu (excellent), I must be in front and U must be in the back, because the sound of U in front of "excellent" cannot be pronounced-the phonetic notation of "losing" must be diū, not duτ.
