SPANGLISH ALERT: ARE YOU A "CRACK" AT ENGLISH?
Although the word "crack" might seem like an English word, native speakers do not use it in the same way as the Spanish do. In Spain, you might hear: "Ronaldo/Messi is a crack" but this form is not used like this in English.
Instead, you would hear something like: "Ronaldo/Messi is an amazing/incredible player". We use "crack" as a verb: "To crack a nut" (physically breaking the shell of the nut) or "To crack a mathematical problem".
Another way to use it is: "This is cracking!!!" which means something is amazing.
Hope that helps!
