Final answer:
Certain words, like 'jointly', 'severally', and 'solidarily', can be used in a promissory note to commit all borrowers for repayment.
Step-by-step explanation:
In a promissory note, certain words can be used to commit all borrowers for repayment. One key word is 'jointly', which means that each borrower is equally responsible for repaying the loan. Another word is 'severally', which means that each borrower is individually responsible for repaying the loan. Finally, the word 'solidarily' can be used, which means that each borrower is collectively responsible for repaying the loan. By including these words in the promissory note, all borrowers are legally obligated to repay the loan.
