Angrily cry out about a bad loss (7)
I believe the answer is:
crossly
'angrily' is the definition.
(I've seen this before)
'out about a bad loss' is the wordplay.
'out' becomes 'cry' (I am not sure about this - if you are sure you should believe this answer much more).
'about' means one lot of letters goes inside another.
'a bad' is an anagram indicator.
'loss' anagrammed gives 'ossl'.
'cry' going around 'ossl' is 'CROSSLY'.
'cry' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for crossly that I've seen before include "Angrily" , "in anger" .)
