Fantastic baller breaks toe - it's okay (9)
I believe the answer is:
tolerable
'okay' is the definition.
(thesaurus)
'fantastic baller breaks toe' is the wordplay.
'fantastic' indicates anagramming the letters (a fantastic or improbable ordering of the letters).
'breaks' means one lot of letters goes inside another (inserted letters break into the word).
'baller' with letters rearranged gives 'lerabl'.
'lerabl' inserted within 'toe' is 'TOLERABLE'.
'it's' is the link.
(Other definitions for tolerable that I've seen before include "Fairly good" , "Mediocre" , "Passable" , "Fair" , "Acceptable" .)
