I'm reading The Pronunciation of Canadian French by Douglas C. Walker and I need help understanding this part:
It is commonplace to observe that in SF the final syllable of the word is stressed, unless it contains a schwa, in which case the penultimate syllable bears the accent. Given the great frequency of deletion of final schwa in colloquial French, the following words of would be accented as indicated:
SF is standard French. Primary stress is indicated by the bolded vowel.
I don't see understand what the author means by the deletion of final schwa that is, I don't understand where was schwa supposed to have been in these examples?
Thanks in advance for your help.
