Still I will take angling gear round river (5)
I believe the answer is:
inert
'still' is the definition.
(not moving)
'i will take angling gear round river' is the wordplay.
'will take' is a charade indicator (letters next to each other).
'angling gear' becomes 'net' (I can't explain this - if you can you should believe this answer much more).
'round' indicates putting letters inside.
'river' becomes 'r' (abbreviation for river).
'net' placed around 'r' is 'nert'.
'i'+'nert'='INERT'
Can you help me to learn more?
(Other definitions for inert that I've seen before include "Devoid of motion or change" , "Slow and apathetic" , "Unreacting" , "Torpid" , "Sluggish, still" .)
