Sloth near Ealing fed last of spaghetti (8)
I believe the answer is:
inaction
'sloth' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
(Other definitions for inaction that I've seen before include "Inertia" , "This is not working" , "Stasis" , "Sluggishness" , "Immobility" .)
