On the outside lane, change direction and gear (6)
I believe the answer is:
tackle
'gear' is the definition.
(I know that tackle is a type of gear)
'on the outside lane change' is the wordplay.
'on' means one lot of letters go next to another.
'the outside' means to remove the middle letters (I've seen 'outside of' mean this).
'change' becomes 'tack' (tack is a kind of change).
'lane' with its middle taken out is 'le'.
'le' put after 'tack' is 'TACKLE'.
'direction and' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for tackle that I've seen before include "Take on; sports gear" , "Try to deal with something awkward - in rugby?" , "Try to deal with fishing gear" , "Take hold" , "Have a go at the one with the ball" .)
