The home improvements have taken what little there is of my spare time 这句中的what是怎么进去

There is (only) a little of my spare time.我只有一点点闲暇时光.
（But）the home improvements have taken it.可是装修却全部把它（这么一点点闲暇时光）全部占用了.
前句用what来改变成感叹句,然后充当take的宾语从句.
口语表达方式,楼主不必太过计较语法问题.
Sorry,没有注意到楼上那么多被追问,可以无视偶 if you like,Give one word to the blank:The home improvements have taken ( ) littlethere is of my spare time。It's 'what' of course! Why not?The word 'llittle' is a pronoun, not an adjective or adverb.The word 'of' must be used here because there is another definite 'my', otherwise it could be just 'a little spare time'.呵呵，就是不用what,请用其他单词, please。------- a word game thatconsused me for years. Now I have got through it.I think another answer is 'the'.If so, the sentence 'there is of my spare time' functions as an attritutive clause, and its relative pronoun is omitted.
