Questions & Answers about kikai ni ijou ga arimasu.

How is this sentence pronounced?

It is pronounced:

きかい に いじょう が あります。
Kikai ni ijō ga arimasu.

A natural English rhythm would sound something like:
ki-kai ni i-joh ga a-ri-ma-su

Notes:

• 機械 = きかい
• 異常 = いじょう
• The ょう in いじょう is a long o sound, so ijō rather than ijo.

Why is に used after 機械?

Here, に marks the place or target where something exists.

So the structure is basically:

• 機械に = in/on/with the machine
• 異常がある = there is an abnormality / there is a problem

A very literal way to think of it is:

At the machine, an abnormality exists.

In natural English, we usually say:

• There is something wrong with the machine.
• The machine has a problem.

So に is not being translated word-for-word as to here. It is showing where the abnormal condition is found.

Why is が used after 異常?
