Playing around with an accent machine, I see that oISHII by itself is zero tone (oISHIINE), whereas oISHIidesune has the accent on the shi.
Although I know the basic rules of the pitch accent, whatever is happening above is completely beyond me. Does anyone know what's happening here?
DEsu has accent on the de, so oISHII + DEsu should be oISHIIDEsu as far as I understand… just like gaKUSEI + DEsu = gaKUSEIDEsu. So… do adjectives work differently, or… what?
