Sense: verb/1
For money actions, paid is the ordinary past form of pay and is the broadest choice. Settled often appears with bills, debts, or accounts, and it suggests that nothing remains unpaid. Covered is more informal and often means one person paid the cost for another person or group. Refunded is different because the money comes back after someone has already paid it. Spent is broader still: it focuses on using money, not always on paying a person, service, or bill directly. You can say Marcus paid the driver, the hotel bill was settled, Nina covered lunch for her friends, the airline refunded the ticket, and Leo spent too much at the night market.
Etymology
Paid is the past form and past participle of pay. The older verb came into English through French from a Latin root linked with calming, satisfying, or settling what is owed. Over time, English used pay for giving money, and paid became the regular form for past-time uses and later adjective uses such as paid work and well-paid staff.
