Lie on bed perhaps being this (4,4)
I believe the answer is:
bone idle
'this' is the definition.
The answer and definition are not the same part of speech.
'lie on bed perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'lie'+'on'+'bed'='lieonbed'
'lieonbed' anagrammed gives 'BONE-IDLE'.
'being' acts as a link.
Can you help me to learn more?
(Other definitions for bone idle that I've seen before include "Very, lazy, almost ossified" , "Utterly lazy, won't do a tap" , "Extremely inactive" , "Altogether lazy, in an ossified way" , "Constitutionally lazy" .)
