Diphthongs are defined as centering or ingliding if a movement of the tongue from a peripheral to a central position occurs.

Diphthongs are defined as closing or upgliding if a movement of the tongue from a low or central to a high (closed) position occurs. There are two variants of closing/upgliding diphthongs:

• front closing/upgliding (2^nd element = high front vowel)
• back closing/upgliding (2^nd element = high back vowel)
