What does これ以上 (kore ijou) mean?

Question

The whole sentence reads

これ以上　シャレてる時間はない

which is from the lyrics of this anime song and, according to this website, means

There's no more time to be fooling around

I understand the first three lines, and the English translation seems to be literal.

I know that これ means "this". According to JGram, 以上 means "as long as", i.e., as long as you are a student 学生である以上は, etc. However, I'm not sure what これ以上 means and whether the これ is the same one that means "this". I think シャレてる時間はない already means "there's no more time to be fooling around".

Answer 1

これ by itself means "this" and これ以上, then means "beyond this" or "more than this". これ以上+neg. means, then, "no more than this".

You could expand the above sentence to

この時間以上(は)シャレてる時間はない。
I don't have time (to fool around), beyond the time I have spent already fooling around.

Just to give another example:

これ以上はできない。
I can't do any more. (lit. I can't do more than this.)

Answer 2

So Rikai-chan says that 以上 means: (n-adv,n-t) not less than; ... and more; ... and upwards; beyond ... (e.g. one's means); further (e.g. nothing further to say); more than ... (e.g. cannot pay more than that); (P)

So it seems it's emphasizing that: beyond this point, there's no more time to fool around.

It seems to be more likely to be in sentence with verbs that are in negative conjugation as well.

Answer 3

Just to add to what has already been said, minna no nihongo, chuukyu 1, chapter 3, translates これ以上 as "any longer".
