Studies accommodating suitable changes again (8)

'changes again' is the definition.
('adapts' is an answer for 'changes' so perhaps 'readapts' is OK for 'changes again')

'studies accommodating suitable' is the wordplay.
'studies' becomes 'reads' ('read' can be a synonym of 'study'**).
'accommodating' is an insertion indicator.
'suitable' becomes 'apt' (I've seen this before).
'reads' placed around 'apt' is 'READAPTS'.
