Recording band being gradually reduced? (8)
I believe the answer is:
tapering
'gradually reduced?' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs can sometimes define each other.
'recording band' is the wordplay.
'recording' becomes 'tape' (tape recording is a kind of recording).
'band' becomes 'ring' (a ring is a band of metal).
'tape'+'ring'='TAPERING'
'being' is the link.
Can you help me to learn more?
(Other definitions for tapering that I've seen before include "Becoming less" , "Becoming gradually narrower like some candles (8)" , "Narrowing to a point" , "thinning out" , "getting less and less" .)
