In English, the noun 'replicate' is pronounced with a schwa (ə) at the end while the verb is pronounced with the diphthong 'eɪ'. The same is true for the word 'duplicate'. Is there a more general trend that I am missing here?
I suppose this isn't quite the same question, but it is similar enough I think to combine: why haven't the verb forms collapsed into using the schwa?
Many thanks from a linguistics newbie.
