Questions & Answers about jitai ga kawarimashita.

How do you read 事態が変わりました?

It is read:

じたい が かわりました。

Breakdown:

• 事態（じたい） = situation, state of affairs, development
• が = subject marker
• 変わりました（かわりました） = changed / has changed

The verb comes from the dictionary form 変わる（かわる）.

What nuance does 事態 have here?

事態 is a bit more serious or formal than a simple situation in everyday English.

It often refers to:

• a state of affairs
• a turn of events
• a development in a matter
• a situation, especially one with some importance or seriousness

So 事態が変わりました can sound more formal or weighty than something like:

• 状況が変わりました = the situation/circumstances changed

Very roughly:

• 事態 = the overall state of events, often in a significant matter
• 状況 = circumstances, conditions, situation more generally

Why is the particle が used instead of を?
