Good angle to enclose ancient stadium where there's no privacy (8,4)
I believe the answer is:
goldfish bowl
'where there's no privacy' is the definition.
The definition suggests a singular noun which matches the answer.
'good angle to enclose ancient stadium' is the wordplay.
'good' becomes 'g' (abbreviation).
'angle' becomes 'fish' (synonyms).
'to enclose' is an insertion indicator.
'ancient' becomes 'old' (similar in meaning).
'stadium' becomes 'bowl' (synonyms).
'g'+'fish'='gfish'
'gfish' placed around 'old' is 'goldfish'.
'goldfish'+'bowl'='GOLDFISH BOWL'
Can you help me to learn more?
