Being a bit pious, a blessing can work (6)
I believe the answer is:
usable
'being a bit pious a blessing can work' is the definition.
I can't judge whether this definition defines the answer.
'being a bit pious a blessing can' is the wordplay.
'being a bit' indicates the answer is hidden within the clue (the answer is formed by a bit of the clue).
'USABLE' is hidden in the letters of 'pious a blessing can'.
Can you help me to learn more?
(Other definitions for usable that I've seen before include "Functional and available" , "Functional, operational" , "not to be discarded?" , "at one's disposal" , "Functioning" .)
