it is

[vredes]

What is the difference between these two following sentences and could you explain to me which one is correct and why?
1.It wouldn't be the crowning achievement it is if he defined himself through decor
2.It wouldn't be the crowning achievement if he defined himself through decor

Thank you

There is a difference in the meaning.
The first sentence says that the achievement is really crowning.

thank you for your reply

Hi,
I've asked this (quite) the same question in another forum, and he/she said if I left out the [it is] it would seem like non-native. Is it right? By the way s/he reconstructs the first sentence like this:

[It wouldn't be the crowning achievement] [that it is] [if he defined himself through decor]

Thank you.

I think in most contexts when without "it is" it should be:
It wouldn't be a crowning achievement if he defined himself through decor.

But I'm a bit numb now, and can easily be wrong. And I am not a teacher.
