@Marleen84722 that's a good question- I'm wondering the same thing. What purpose does the Apostrophe serve at the end?
And does it have a sound?
It's a glottal stop. It's like the hitch in the voice in "uh-oh."
Hágoónee' means good bye not see you later hágoóshilaá means see u later
Hágoónee' sounds a little like "have a good day"
Why do you need the ' at the end of a word? What sound does it symbolize?
It is a gladal stop that means a sudden stop
