It is usually read:
だいたいき を かります。
More naturally, without the learning spaces:
代替機を借ります。
- 代替機 = だいたいき
- を = object marker
- 借ります = かります
You may occasionally hear different pronunciations of 代替 in real life, but だいたいき is the standard reading to learn first here.
代替機 means a replacement device, substitute unit, or loaner device.
It is often used when:
- your phone, computer, or another machine is being repaired
- a company gives you another device to use temporarily
- one machine is used in place of another
The parts are:
- 代替 = substitution / replacement
- 機 = machine / device / unit
So 代替機 is not just any machine; it is a machine or device used instead of the original one.
