5. Palato-Alveolar (/sh/, /zh/, /ch/, /jh/, /r/):
The palato-alveolar sounds [sh] (shrimp), [ch] (china), [zh] (Asian), and [jh] (jar) are made with the blade of the tongue against this rising back of the alveolar ridge
tongue is between alveolar ridge and hard palate
2 fricatives, 2 affricates, 1 retroflex
retroflex has “depression” midway along tongue
the palato-alveolar fricatives tend to have strong energy due to weak constriction allowing large airflow
