How do you say im going to tell about in Hawaiian?

There isn't a direct, single phrase in Hawaiian that perfectly translates "I'm going to tell about" in the way you might use it in English. The closest you can get depends on the context:

Option 1: Focus on the action of telling

* E haʻi aku ana au iā ʻoe e pili ana i... (Literally: "I am telling you about...") This emphasizes the act of telling.

Option 2: Focus on the intention to tell

* E haʻi aku ana au iā ʻoe e pili ana i... (Literally: "I am going to tell you about...") This emphasizes the future action.

Option 3: Use a specific verb instead of "tell"

* E hōʻike aku ana au iā ʻoe e pili ana i... (Literally: "I am going to show you about...") This is suitable if you're demonstrating or explaining something.

* E wehewehe aku ana au iā ʻoe e pili ana i... (Literally: "I am going to explain to you about...") This emphasizes explaining.

Remember:

* "e pili ana i..." translates to "about..."

* "iā ʻoe" means "to you"

Example:

* E haʻi aku ana au iā ʻoe e pili ana i ka moʻolelo o Hawaiʻi. (I am going to tell you about the history of Hawaiʻi.)

Note: Hawaiian grammar is quite different from English. This is just a starting point. For a more precise translation, consider providing more context about what you're going to tell about.
