Pedestrian being initially very fussy (5)
I believe the answer is:
banal
'pedestrian' is the definition.
(I've seen this before)
'being initially very fussy' is the wordplay.
'initially' indicates taking the first letters.
'very fussy' becomes 'anal' (anal can mean overly fussy or orderly. I am not sure about the 'very' bit.).
The initial letter of 'being' is 'b'.
'b'+'anal'='BANAL'
Can you help me to learn more?
(Other definitions for banal that I've seen before include "tired" , "lacking interest?" , "boringly dull" , "flat" , "Mundane" .)
