Humble way followed by saint (6)
I believe the answer is:
modest
'humble' is the definition.
('modest' can be a synonym of 'humble')
'way followed by saint' is the wordplay.
'way' becomes 'mode' ('mode' can be a synonym of 'way'**).
'followed by' means one lot of letters go next to another.
'saint' becomes 'st'.
'mode'+'st'='MODEST'
(Other definitions for modest that I've seen before include "Bashful" , "Not conceited, unassuming" , "Unassuming or decent" , "Unassuming; limited" , "Inexpensive" .)
