First Lady to beam for eternity (4,5)
I believe the answer is:
ever after
'eternity' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'first lady to beam' is the wordplay.
'first lady' becomes 'eve' (Biblical first woman).
'to beam' becomes 'rafter' (rafter is a kind of beam).
'eve'+'rafter'='EVER AFTER'
'for' is the link.
Can you help me to learn more?
(Other definitions for ever after that I've seen before include "from then on, till the end of time" , "for good?" .)
