Steady way worker follows study (8)
I believe the answer is:
constant
'steady' is the definition.
('constant' can be a synonym of 'steady')
'way worker follows study' is the wordplay.
'way' becomes 'st' (**).
'worker' becomes 'ant' (worker is a type of ant).
'follows' says to put letters next to each other.
'study' becomes 'con' (I've seen this before).
'st'+'ant'='stant'
'stant' after 'con' is 'CONSTANT'.
(Other definitions for constant that I've seen before include "Never-ending" , "Continuous" , "staying the same" , "Continuing unvarying" , "Perpetual" .)
