Step taken by wise man in hall (7)
I believe the answer is:
passage
'hall' is the definition.
(thesaurus)
'step taken by wise man' is the wordplay.
'step' becomes 'pas' (I've seen this before).
'taken by' says to put letters next to each other.
'wise man' becomes 'sage' (sage is a kind of wise man).
'pas'+'sage'='PASSAGE'
'in' is the link.
(Other definitions for passage that I've seen before include "Way through; part of text" , "Section of musical or literary work" , "Sea or air journey" , "Book extract; transit" , "Sea/air journey" .)
