Why 'Cats' and 'Dogs' Don't Rhyme

Here's a pattern Portuguese speakers often miss: English endings spelled '-s' actually change sound depending on what comes before them. After a voiceless sound like 'cat,' it's a crisp 's' ('cats'). After a voiced sound like 'dog,' it becomes a 'z' buzz ('dogz'). And after sounds like 'ch' or 'sh,' you add a whole extra syllable, 'iz' ('watches'). Saying every one of these the same way can make your endings sound flat. Try the three together: 'cats' (s), 'dogs' (z), 'watches' (iz), feeling the difference in your throat — buzzing for the z, silent for the s. For two minutes today, say 'books, cars, dishes' slowly, checking that your voice buzzes on 'cars' but stays quiet on 'books.' This tiny shift makes your grammar endings sound sharp and natural. You've got the pattern — now just practice it into habit.
