Dull lawyer gives up part-way through (4)
I believe the answer is:
grey
'dull lawyer gives up part-way through' is the definition.
I can't tell whether this definition defines the answer.
'dull lawyer gives up part' is the wordplay.
'part' says the answer is hidden in the clue.
'up' says the letters should be written backwards (in down clue: letters go upwards).
'yerg' is hidden within 'dull lawyer gives'.
'yerg' in reverse letter order is 'GREY'.
Can you help me to learn more?
(Other definitions for grey that I've seen before include "Black-white tone" , "Old - colourless" , "Intelligence" , "Colour (of fifty shades?)" , "Aged; cloudy" .)
