"male cadere"? I didn't know the expression before. What does it precisely mean, dear?

I would use a verb "vincitur" or "perditur".

It's "to fail, to finish badly".
But I'm going to change as well...

Oh, I see. But is it "male cadere" or "male cedere"? I wonder, because from the form you put I can guess it is the second verb and I can't believe it can change the meaning so much taking "male"...

And one more proposition of mine: "deficit". But you decide, dear.

Uhm, I think I'm going to use "deficit". I like it!
