Following is a detailed example of how the questionnaire works. Let's consider the evolution of n. We suggest two types of changes ([n to ŋ] and the loss of n [n to zero]).

Sonorants, Nasals : n >
 ŋ

 zero

 other

You may want to specify that the weakening of n to the velar nasal ŋ [n to ŋ ] is frequent word-finally, whereas the loss of n [n to zero] is frequent syllable-finally through the transfer of the nasalization feature to the previous vowel.
Sonorants, Nasals : n >
 ŋ

 zero

 other

(specify)

If you have another type of change to mention, check the option "other" and specify the change in the text box.

At the end of each section, you may add any comment you have to make about the evolution of the particular class of sounds considered. For exemple, you may want to mention that nasals are very stable word-initially.
