When models that have lost their shape are employed? (6)
I believe the answer is:
seldom
'when' is the definition.
Both the definition and answer are adverbs. Perhaps there's an association between them I don't understand?
'models that have lost their shape are employed?' is the wordplay.
'models' anagrams to 'SELDOM'.
But, I am not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for seldom that I've seen before include "Once in a blue moon" , "Not often, infrequently" , "Models (anag)" , "Only occasionally" , "Not 21" .)
