Time (100 years) in enclosure like each other across answer? (8)
I believe the answer is:
birdcage
'enclosure like each other across answer?' is the definition.
I can't judge whether this defines the answer.
'time 100 years' is the wordplay.
'time' becomes 'bird' (both are slang for a prison sentence).
'100' becomes 'c' (Roman numeral).
'years' becomes 'age' (period of many years).
'bird'+'c'+'age'='BIRDCAGE'
'in' is the link.
Can you help me to learn more?
(Other definitions for birdcage that I've seen before include "with plenty of bars with high-fliers inside" , "Small aviary" , "Enclosure for a budgie, say" , "Home for a pet" , "Polly's home perhaps" .)
