Did you learn English in school? This language hardly changes the forms of verbs or nouns in ways that affect meaning. Lucky learners of English or Malay can easily string words together and communicate with limited vocabulary. But if you studied an “inflected” language like German,
Spanish, Russian, or Greek, you found that communication with just a few words is difficult. Listeners expect the correct endings of verbs and nouns to know who said what to whom and when. These “inflections,” or pattern changes, must be learned early on.
