The two most common adjectives we can use when describing that something is hard for us would be, "hardest," or, "most difficult." Notice that in these two examples we are using the superlative but they take different forms. Hard can have the superlative at the end with an -est ending whereas difficult cannot so the superlative "most," must come before.
