A more thorough explanation:

Definition: A subtenant is a person who rents a property from a sublessee, who is already renting the property from the original landlord. Essentially, a subtenant is a tenant of a tenant.

For example, let's say that John is renting an apartment from the landlord. However, John needs to move out of the apartment before his lease is up. Instead of breaking his lease, John decides to sublease the apartment to Sarah. Sarah is now the sublessee, and John is the sublessor. If Sarah decides to rent out a room in the apartment to her friend, that friend would be the subtenant.

Another example would be if a business owner rents a commercial space from a landlord, but then decides to sublease a portion of that space to another business. The second business would be the sublessee, and any employees or customers of that business would be considered subtenants.

These examples illustrate how a subtenant is someone who is renting a property from someone who is already renting that property from the original landlord. It's important to note that subtenants have fewer rights and protections than the original tenant, as they are not in a direct agreement with the landlord.
