Approach steps in wall, perhaps, speaking (5)
I believe the answer is:
style
'approach' is the definition.
(thesaurus)
'steps in wall perhaps speaking' is the wordplay.
'steps in wall perhaps' becomes 'stile' (set of steps letting walkers climb over a wall).
'speaking' indicates a 'sounds like' (homophone) clue.
'stile' sounds like 'STYLE'.
(Other definitions for style that I've seen before include "Fashion - flair" , "Manner or look" , "Phraseology" , "Manner; elegance" , "Designate" .)
