Industrious man who resembles Herb we hear? (8)
I believe the answer is:
diligent
'industrious man who resembles herb we hear?' is the definition.
'diligent' can be an answer for 'industrious' (I've seen this before). I am unsure of the remainder of the definition.
'industrious man' is the wordplay.
'industrious' becomes 'dili' (I am not sure about this - if you are sure you should believe this answer much more).
'man' becomes 'gent' (gent is a kind of man).
'dili'+'gent'='DILIGENT'
Can you help me to learn more?
(Other definitions for diligent that I've seen before include "Steady in application and industry" , "Showing care and effort" , "Taking trouble" , "Steady and hard-working" , "Working hard and conscientiously" .)
