A more thorough explanation:

inquilinus

An inquilinus is someone who rents or lives in another person's house or apartment, especially in urban areas.

• John is an inquilinus because he rents an apartment from his landlord in the city.
• Maria is an inquilinus because she lives in a house owned by her friend in the city.

These examples show that an inquilinus is someone who lives in a property owned by someone else. They pay rent to the owner of the property and are not the legal owner themselves. This term is often used in urban areas where many people rent apartments or houses instead of owning them.
