A puzzling layout? Daughter is gobsmacked (6)
I believe the answer is:
amazed
'gobsmacked' is the definition.
(I've seen this before)
'a puzzling layout? daughter' is the wordplay.
'puzzling layout?' becomes 'maze' (I can't explain this - if you can you should give a lot more credence to this answer).
'daughter' becomes 'd' (genealogical abbreviation).
'a'+'maze'+'d'='AMAZED'
'is' is the link.
Can you help me to learn more?
(Other definitions for amazed that I've seen before include "Confounded" , "Greatly surprised or astonished" , "Greatly surprised, never would have thought it" , "Flabbergasted" , "Gobsmacked" .)
