What the parameters before brackets mean?

In the documentation you can insert data inside a table with the following syntax:

(insert table-name id {"parameter":parameterValue})

But here, in this example i have extra values in parameters before the brackets.

(insert loans-inventory (inventory-key loanId entityName) {"balance":loanAmount})

What (inventorty-key loanId and entintynName) syntax mean? (inventory-key) is a function.

inventory-key function

(defun inventory-key (loanId:string owner:string)
(format "{}:{}" [loanId owner]))

(inventory-key loanId entityName) is a call to the inventory-key function with loanId and entityName as arguments. It all returns a value that serves the purpose as a key to the row that is being inserted in the table.

The key used comes from the output of the inventory-key function, which looking at the example (loans tutorial) it is a function that returns a string in the format of loanId:owner, probably to make it unique.
