"Keoki cleans at 1:30 midday."
Translation:Hoʻomaʻemaʻe ʻo Keoki i ka hapalua hola ʻekahi o ke awakea.
Its a shame the system lets you get away with it 99% of the time and then suddenly forces you to use them in some cases. Other than that i agree the 'okina are an important part of the language and i know where to put them. Its just that its incredibly inconvenient and time consuming to type them. At least on a phone keyboard which happens to be what im using. On a piece of paper i wouldnt even think about leaving them out.
Most cellphones allow you to add the Hawaiian keyboard to your phone. On the iPhone, you will see the globe icon when you begin to type in duolingo. You just click on it and add Hawaiian.
