Being awkward, mean to get the last word (4)
I believe the answer is:
amen
'the last word' is the definition.
(I've seen this before)
'being awkward mean' is the wordplay.
'being awkward' indicates anagramming the letters.
'mean' with letters rearranged gives 'AMEN'.
'to get' is the link.
(Other definitions for amen that I've seen before include "So let it be" , "statement of affirmation" , "Conclusion of prayer" , "Name for prayer's end" , "Churchgoer's assent?" .)
