Fittingly adapted play about the outback (5)
I believe the answer is:
aptly
'fittingly' is the definition.
(I've seen this before)
'adapted play about the outback' is the wordplay.
'adapted' is an anagram indicator.
'about' is an insertion indicator.
'the outback' becomes 't' (I can't justify this - if you can you should believe this answer much more).
'play' anagrammed gives 'aply'.
'aply' placed around 't' is 'APTLY'.
Can you help me to learn more?
(Other definitions for aptly that I've seen before include "In suitable fashion" , "as is fitting" , "Suitably" , "In suitable form" , "In an appropriate way" .)
