Alleging one piece of valuable pottery gets put inside (8)
I believe the answer is:
imputing
'alleging' is the definition.
Although both the answer and definition are present participle verbs, I cannot understand how they can define each other.
'one piece of valuable pottery gets put inside' is the wordplay.
'one piece of valuable pottery' becomes 'img' (I am not sure about this - if you are sure you should believe this answer much more).
'gets' means one lot of letters goes inside another (gets can mean captures or absorbs).
'inside' becomes 'in'.
'put'+'in'='putin'
'img' going around 'putin' is 'IMPUTING'.
Can you help me to learn more?
(Another definition for imputing that I've seen is " Ascribing or charging".)
