there was two options: kēia and kela I accidentally clicked kela and it said I had a typo, but then I did it again and it said it was wrong
"Kela" means "that", but is a particular class of "that." Kela indicates that the object is far from the speakers. Kena indicates that the object is close or within reach.
There should be little buttons on the site that you click for the vowels with the macrons. If you are on a mobile device, that may be the problem if you do not have those buttons.
