To find out how hints are phrased and what their categories are, it's best to look at the source code directly. It is not required to have coding experience to be able to read this. Let's take a look at the Kokiri Sword:
'Kokiri Sword': (["a butter knife", "a starter slasher", "a switchblade"], "the Kokiri Sword", 'item'),
The first element of this line is the name of the item in the spoiler log: Kokiri Sword. The second element, enclosed by square brackets [...], is what the randomizer will use if "Clearer Hints" is disabled. The next element, the Kokiri Sword, is what will be used if "Clearer Hints" is enabled. The final element item is the category
Now let's take a look at the location for the item on Darunia:
'GC Darunias Joy': ("a #groovin' goron# gifts", "#Darunia's dance# leads to", ['overworld', 'sometimes']),
As before the first element, GC Darunias Joy, is the name of the location in the spoiler log, the second element, a #groovin' goron# gifts, is what the randomizer will use if "Clearer Hints" is disabled, the third element, #Darunia's dance# leads to, is what will be used if "Clearer Hints" is enabled, and the final element, ['overworld', 'sometimes'], are the categories.
All items and locations will follow this pattern. However, there are a couple of locations that will become always hints under certain conditions. Those hints and the conditions can be found in the table below. Keep in mind that when it says "required by the settings to beat the game" it only considers Rainbow Bridge and Light Arrows Cutscene (LACS) conditions, and not whether that location (e.g. 50 skulls) is logically required to beat the game because it has an item on it.
