The word tough comes from Old English tōh, meaning strong, firm, or durable. Over centuries, its spelling stayed the same, even though pronunciation changed.

Tuff, on the other hand, has two roots:

1. A slang spelling of tough, popular in casual writing.
   
2. A geology term, from Italian tufo, meaning a type of volcanic rock.
   

This is why spelling differences exist—tough is historical and standard, while tuff developed later for specific or informal use.
