Family keeping large pots fired here (4)
I believe the answer is:
kiln
'pots fired here' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'family keeping large' is the wordplay.
'family' becomes 'kin' (synonyms).
'keeping' is an insertion indicator.
'large' becomes 'L' (eg in clothes sizes).
'kin' placed around 'l' is 'KILN'.
Can you help me to learn more?
(Other definitions for kiln that I've seen before include "Drying furnace" , "Oven for hardening and drying" , "Baker" , "Industrial furnace" , "Oven for firing pottery" .)
