Possibly show me love in one way or another (7)
I believe the answer is:
somehow
'in one way or another' is the definition.
(I've seen this before)
'possibly show me love' is the wordplay.
'possibly' is an anagram indicator.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'show'+'me'+'o'='showmeo'
'showmeo' anagrammed gives 'SOMEHOW'.
(Other definitions for somehow that I've seen before include "By one means or another" , "One way or another" , "In a way not yet specified" , "By hook or by crook" , "In an unspecified manner" .)
