Eat up new bosses (6)
I believe the answer is:
obsess
'eat up' is the definition.
Although both the answer and definition are verbs in their base form, I don't understand how one could define the other.
'new bosses' is the wordplay.
'new' is an anagram indicator.
'bosses' with letters rearranged gives 'OBSESS'.
Can you help me to learn more?
(Other definitions for obsess that I've seen before include "Prey on" , "Be constantly talking about" , "Constantly worry (about something)" , "Occupy the thoughts persistently" , "Haunt - preoccupy" .)
