동격절에 쓰이는 that은 생략될 수 없을까?

동격절 that은 생략이 안된다는 문법책들이 있습니다. 사실일까요? 

결론부터 말씀 드리자면 생략 될 수 있습니다. 다만 절의 특성이 restrictive해야 합니다. A Student's Grammar of The English Language에는 동격절의 that이 nonrestrictive (앞에 컴마 있는 경우) 에 생략이 안된다고 설명이 되어 있지 restrictive에서 생략이 안된다는 말은 없습니다. 그리고 Corpus를 검색해봐도 엄청난 수의 생략 문장이 검색됩니다. 따라서 우리나라 문법책에 나와있는 동격절 that이 생략 안된다는 말은 맞다고 할 수 없습니다. 왜냐면 그 때의 동격절이 restrictive이기 때문입니다. 

논문에서 관련 부분을 찾아봤습니다. 혼란을 일으킬 수 있는 경우를 제외하고 that의 생략은 비교적 자유롭습니다. 아래 Impossible을 제외하고 아래 Possible은 생략이 되는 경우입니다. 

8.4.5 That-omission in complements to nouns

• Below is a summary of some of the data from the literature and a very preliminary corpus

search.

• It seems clear that that-less complements of N are possible, and in some cases even frequent.

• There are restrictions on when that-omission is possible (which may be similar to the restrictions

on embedded V2 in German), and a careful investigation of these restrictions is still

outstanding.
