Moving in readiness, catching husband's rousing remark (4,3,5)
I believe the answer is:
rise and shine
'rousing remark' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'moving in readiness catching husband's' is the wordplay.
'moving' indicates an anagram (letters are moved around).
'catching' indicates putting letters inside.
'husband' becomes 'h' (abbreviation).
'in'+'readiness'='inreadiness'
'inreadiness' anagrammed gives 'riseandsine'.
'riseandsine' going around 'h' is 'RISE AND SHINE'.
Can you help me to learn more?
(Other definitions for rise and shine that I've seen before include "Bounce out of bed" , "as will the sun bright and early?" , "Exhortation to get out of bed" , "Look lively" , "Wake up" .)
