Back road beside quarry -- deserted narrowboat just round the corner (8)
I believe the answer is:
imminent
'just round the corner' is the definition.
I can't judge whether this definition defines the answer.
'back road beside quarry deserted narrowboat' is the wordplay.
'back' says the letters should be written backwards.
'road' becomes 'mi'.
'beside' says to put letters next to each other (I've seen this in other clues).
'quarry' becomes 'mine'.
'deserted' says to hollow out the word (remove centre letters).
'narrowboat' with its centre taken out is 'nt'.
'mi' backwards is 'im'.
'im'+'mine'+'nt'='IMMINENT'
Can you help me to learn more?
(Other definitions for imminent that I've seen before include "About to happen, looming" , "Liable to occur soon" , "Close at hand, about to occur" , "About to occur, any time now" , "now expected" .)
