Translation:Mao ka ua.
I don't understand when it is ke, ko or ka. Can anyone help?
I don't know about ko. Ke is "the" before words that start with k, e, a, or o. Ka is "the" before words that start with h, i, l, m, n, u, or w. Before p and ' it is usually ka, but there are some exceptions that need to be memorized individually.
