Questions & Answers about kore wa shinkokuna jitai desu.

How do you pronounce これは深刻な事態です?

It is pronounced:

kore wa shinkoku na jitai desu

A few notes:

• これ = kore
• は is written ha, but in this use it is pronounced wa
• 深刻な = shinkoku na
• 事態 = jitai
• です = desu
  In careful speech, the u in desu can be very light, so it may sound a bit like des.

Why is は pronounced wa here?

Because は is being used as the topic particle, not as part of a regular word.

In modern Japanese:

• when は is part of a word, it is usually pronounced ha
• when は marks the topic of the sentence, it is pronounced wa

So in これは深刻な事態です, これ is the topic, and は shows that. That is why you say kore wa, not kore ha.
