Paul is the man who we believe has the best understanding of what it is that m
akes our products different from others on the market.
請問 what it is 中的 it is 可以省略嗎？
that makes… 是形容詞子句還是名詞子句？
煩請解惑，感謝。

1. 如果要省略，it is that 要同時都拿掉2. 形容詞子句 修飾前面的what

that 引導形容詞子句，為何不直接放在what後面？it is是指什麼？

句形是Paul ... best understanding of (something)然後 something = what it... market 這一句it is 就是指那個 what (倒裝句) 那個what就是that makes our products different的東西原句是 It is XXX that makes our product different.現在XXX沒寫出來，用what代替。
