'revealing' is the definition.
The definition and answer can be both to do with communicating as well as being present participle verbs.
Maybe they are linked in a way I don't understand?

'drama ultimately bbc boss acquires with german money' is the wordplay.
'ultimately' suggests the final letters.
'bbc boss' becomes 'DG' (short for director-general of the BBC).
'acquires' indicates putting letters inside.
'with german' becomes 'mit' ('with' in German).
'money' becomes 'tin' (old-fashioned slang term for money).
The final letter of 'drama' is 'a'.
'mit'+'tin'='mittin'
'dg' going around 'mittin' is 'dmitting'.
'a'+'dmitting'='ADMITTING'
