'corporations?' is the definition.
The definition and answer can be both body parts as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'worryingly bad signs' is the wordplay.
'worryingly' indicates anagramming the letters (letters are disturbed or worried).
'signs' becomes 'omens' (omen is a kind of sign).
'bad' is an anagram of 'abd'.
'abd'+'omens'='ABDOMENS'

'for' is the link.

Can you help me to learn more?

(Another definition for abdomens that I've seen is " Stomachs".)

I've seen this clue in The Guardian.
