leesing

I’m not aware of a widely recognized concept or term named "leesing" in standard references. Could you clarify what you mean? Possible options:

- Leasing (the contractual arrangement to rent property or equipment)

- Leesing as a proper noun (a surname, place, or organization)

- A fictional or niche term you’ve created

If you provide context or specify which sense you intend, I can draft a concise, neutral wiki-style article under 300 words. If you’d like, I can also write about leasing as a real-world topic in the meantime.
