In the Lakota language it is essential to understand pronunciation in order to fully express emotions and to make a statement with feeling.
Feelings are important in language.
We can say a thousand words and not mean a single one if our feelings are not in it. Whether listening to English or Lakota speakers, you can tell when they effectively use their language because you can feel their feelings. In addition to emotions and feelings, language reflects environment. It expresses philosophy. It affirms spirituality.
