Possibly show me love in one way or another (7)
I believe the answer is:
Here is my best explanation:
'one way or another' is the definition.
(I've seen this before)
'possibly show me love' is the subsidiary indication.
'possibly' is an anagram indicator.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'showmeo' anagrammed gives 'somehow'.
'in' is the link.
(Other definitions for somehow that I've seen before include "For an unknown reason; so who, me? (anag.)", "By one means or another", "One way or another", "In a way not yet specified", "one way or another", "For some unspecified reason", "By hook or by crook", "In an unspecified manner", "By unspecified means" and "In an unspecified way".)
