Walk right and left, badly lost outside (6)
I believe the answer is:
stroll
'walk' is the definition.
(stroll is a kind of walk)
'right and left badly lost outside' is the wordplay.
I cannot quite understand how this works, but
'right' could be 'r' (common abbreviation) and 'r' is found within the answer.
'left' could be 'l' (common abbreviation) and 'l' is found in the answer.
an anagram of 'lost' is 'stol' which is within the left over letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for stroll that I've seen before include "Constitutional" , "A quiet, pleasant walk" , "A pleasant and leisurely walk" , "Meander" , "swan" .)
