If you're looking for a suffix to express the idea of "hurry" or "speed," you could use:
* -ly: This suffix is often used to create adverbs, indicating a manner of doing something. For example, "quickly", "rapidly", "swiftly".
* -ing: This suffix can also be used to create adverbs, and often implies a continuous or ongoing action. For example, "rushing", "dashing", "scurrying".
It really depends on the specific context and the word you're trying to create!
