In a way, nothing for me to make a gesture about (7)
I believe the answer is:
somehow
'in a way' is the definition.
(I've seen this before)
'nothing for me to make a gesture about' is the wordplay.
'nothing' becomes 'O' (O resembles 0).
'for' means one lot of letters go next to another.
'to make a gesture' becomes 'show' (I can't justify this - if you can you should believe this answer much more).
'about' is an insertion indicator.
'o'+'me'='ome'
'ome' inserted inside 'show' is 'SOMEHOW'.
Can you help me to learn more?
(Other definitions for somehow that I've seen before include "For some unspecified reason" , "In an unspecified way" , "By unspecified means" , "For an unknown reason; so who, me? (anag.)" , "In an unspecified manner" .)
