The pay that supports you is made in payments. Whether you make payments to keep your house or your car, or you get payments from your boss, they keep you going.
This is a combination of the on'yomi reading of 支 and the kun'yomi reading of 払. You've learned them both, so you know this too!
How would you like to pay?
Please make payments by card.
Thank goodness, now I can pay my bills!
