Soft magic systems are magic systems where the definition and effect of magic is very vague. To put it simply: in the end you can just say “a wizard did it” to everything. Examples: Lord of the Rings, Harry Potter
Hard magic systems on the other hand have logical explanations and defined limitations, which allows the reader to think about what happens. Example: Full Metal Alchemist
Personally, I prefer very hard magic systems. In my novel series it even goes as far that I already thought about “scientific” explanations based on biochemistry.
What magic systems do you prefer? Rather Hard or rather Soft? Do you have any other clear examples for each of these two systems? Explain the magic system in your story and give your reasoning why it’s soft/hard.
