Awful brats also curse (9)
I believe the answer is:
albatross
'curse' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'awful brats also' is the wordplay.
'awful' indicates anagramming the letters.
'brats'+'also'='bratsalso'
'bratsalso' with letters rearranged gives 'ALBATROSS'.
Can you help me to learn more?
(Other definitions for albatross that I've seen before include "Sea bird" , "shot by elderly sailor" , "potentially a disaster if one's damaged at sea" , "High-flyer" , "Large oceanic bird" .)
