There's no direct translation of "I hate" in Hawaiian that carries the same intensity or negativity as the English phrase.
However, you could express dislike or strong disapproval using phrases like:
* ʻAʻole au makemake iā ia. (I don't like it.)
* ʻAʻole au makemake iā ʻoe. (I don't like you.)
* He mea ʻinoʻino ia iaʻu. (It is disgusting to me.)
Remember, these phrases convey a strong aversion but don't translate directly to "hate."
If you want to express a feeling of strong negative emotion, it's best to use more descriptive language or consider the specific context of what you're trying to express.
