sentences:  (Compare how T in English is pronounced like "sh" when followed by -ion in words like "station", "revolution", or how "due"/ "dew" and "Jew" are pronounced identically by many English speakers).-as, -is, -ys (masculine)
  
  Note that the -e ending for the vocative singular applies only to common nouns; proper nouns take the ending -ai.So, for example "Jonas" = 'John' [nominative] and "Jonai!"
