"Saturday is a holiday."
Translation:He lānui ka Pōʻaono.
Here's a great explanation that I just copied to save from another lesson (from jdcowan, bless him!):
He is used almost exactly like 'O. The difference is that if one of the terms is indefinite (uses "a" in English instead of "the"), then you have to list it first and put He on it instead of 'O ka: 'O ka lānui ka lā o ka hōʻike. - "The day of the show is the holiday." He lānui ka lā o ka hōʻike. - "The day of the show is a holiday." Aia ka lā o ka hōʻike ma ka lānui. - "The day of the show is on the holiday."
'O ka Po'aono i ka lānui.
"Saturday is on the holiday."
If "i" is eliminated, then it would qualify as an equational, but it would translate to:
'O ka Po'aono ka lānui.
"Saturday is the holiday."
I don't know!!! I'm having the same trouble. For a long time, sentences with "equivalent" statements [i.e. Saturday is football day.] stressed starting with "is" and then the LAST part of the sentence... then the FIRST part of the sentence in translation. Now, with the days and months, they threw all that out the window. Mak511906 is right - the syntax is all over the place and things are marked wrong when we use perfectly "standard" syntax from what we learned in the past. Trying to make sense of it all is confusing and downright discouraging. I used to think that "Aia" meant "there is" but it's not consistent. I used to think that " 'O " meant "is" but they'll mark it wrong and use "He" instead. I don't know when to use "He" anymore because it's not used as "is" consistently. Grrrrrr! It's almost enough to make me QUIT!
Although it says I got it right, it tells me I have a typo, which I do. But the correct spelling it gives me to show that I have a typo is "He lānui ko Pōʻaono." My typo was not in the word "ka", I typed that correctly, but it is underlined in the example - it seems to be telling me that I should have typed "ko". That looks like an error. Is this sentence with "ko" mistakenly entered as a correct answer in the course?
Amazing, nobody has even tried to answer all your questions. I'll try by giving examples for he / ʻo / aia related to this same sentence without trying to use grammatical terms.
He lānui ka Pōʻaono. = Saturday is A holiday.
ʻO ka Pōʻaono ka lānui. = Saturday is THE holiday.
Aia ka lānui i ka Pōʻaono. = The holiday is on Saturday.
These are the most basic translations using those three words, and if the English is given, you should use the sentence pattern given here that matches it. Does that clarify anything????
