Only occasionally do we get new models (6)
I believe the answer is:
seldom
'only occasionally' is the definition.
(I've seen this before)
'do we get new models' is the wordplay.
'models' can be anagrammed to 'SELDOM'.
But, I am not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for seldom that I've seen before include "Models (anag)" , "on rare occasions" , "Alluvium" , "Once in a blue moon" , "Not very often, rarely" .)
