Ways in which empty nester can't see changes? (9)
I believe the answer is:
entrances
'ways' is the definition.
(entrance is a kind of way)
'empty nester can't see changes?' is the wordplay.
'empty' means to remove the middle letters.
'changes?' indicates an anagram (I've seen 'change' mean this).
'nester' with its middle taken out is 'nr'.
'nr'+'cant'+'see'='nrcantsee'
'nrcantsee' anagrammed gives 'ENTRANCES'.
'in which' acts as a link.
(Other definitions for entrances that I've seen before include "Charms" , "Delights" , "make appearances on stage" , "Transports" , "Fills with delight" .)
