Can you identify the sets of sounds that regularly precede each of these alternative pronunciations of the plural ending? What features do each of these sets have in common?
The use of plural -s in English has three different, but very regular, phonological alternatives. We add /s/ to words like bat, book, cough and ship. We add /z/ to words like cab, cave, lad, rag and thing. We add /əz/ to words like bus, bush, church, judge and maze.
Please help I'm so confused!
