thanks!

It depends on the context in which you use each word. 'Hard' and 'difficult' can mean the same thing when used to describe something that requires a great deal of effort, such as a solving a complex math problem. But 'hard' can also be used to describe an object that is solid, firm, or not easily broken. For example, a rock is hard. 'Difficult' can also be used to describe a person if they are not easy to please. I hope that helps... :)

The word 'hard' can be both --among other things-- an adjective to describe the quality of a material substance or to describe the difficulty of a challenge. For example, I can say, "the table is hard" or, "that was a hard kick", or "that was a hard test". The word "difficult" is more specific to the quality of the challenge, task, obstacle, or situation at hand. For example, I can say, "that was a difficult test", or "that was a difficult day," or "it's a difficult conversation to have". Hope that helps!
