Home at ten, horribly worn out (9)
'worn out' is the definition.
(motheaten can mean worn out or shabby)
'home at ten horribly' is the wordplay.
'horribly' is an anagram indicator (a horribly wrong version of the letters).
'home'+'at'+'ten'='homeatten'
'homeatten' with letters rearranged gives 'MOTHEATEN'.
(Another definition for motheaten that I've seen is " Looking shabby".)
'worn out' is the definition.
'moth eaten' can be an answer for 'worn' (thesaurus). I am not certain of the 'out' bit.
'home at ten horribly' is the wordplay.
'horribly' indicates anagramming the letters (a horribly wrong version of the letters).
'home'+'at'+'ten'='homeatten'
'homeatten' anagrammed gives 'MOTH-EATEN'.
Can you help me to learn more?
(Other definitions for moth-eaten that I've seen before include "Falling to bits" , "Old, in bad condition" , "Damaged by insects" , "Showing severe signs of wear and tear" , "Old and worn" .)
