Possibly play about half of it appropriately enough (5)
I believe the answer is:
aptly
'possibly play about half of it appropriately enough' is the definition.
I can't tell whether this definition defines the answer.
'possibly play about half of it' is the wordplay.
'possibly' is an anagram indicator.
'about' is an insertion indicator.
'half of' indicates taking half.
'play' with letters rearranged gives 'aply'.
'it' with half the letters taken is 't'.
'aply' enclosing 't' is 'APTLY'.
Can you help me to learn more?
(Other definitions for aptly that I've seen before include "Suitably" , "Fittingly" , "In a competent manner" , "In suitable fashion" , "as is fitting" .)
