Fed up with shifting dirt out of the way (5)
I believe the answer is:
tired
'fed up' is the definition.
(thesaurus)
'shifting dirt out of the way' is the wordplay.
'shifting' indicates an anagram.
'out of' indicates putting letters inside (some letters on the outside of others).
'the way' becomes 'e' (Compass direction - East).
'dirt' with letters rearranged gives 'tird'.
'tird' going around 'e' is 'TIRED'.
'with' acts as a link.
(Other definitions for tired that I've seen before include "Spent" , "getting bored" , "Ready to drop" , "Worn-out" , "Exhausted" .)
