Member with gold duck houses is only lasting a short time (8)
I believe the answer is:
temporal
'only lasting a short time' is the definition.
I can't judge whether this defines the answer.
'member with gold duck houses' is the wordplay.
'member' becomes 'MP' (Member of Parliament).
'with' says to put letters next to each other.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'duck' becomes 'teal' (teal is a type of duck).
'houses' is an insertion indicator.
'mp'+'or'='mpor'
'mpor' going into 'teal' is 'TEMPORAL'.
'is' is the link.
Can you help me to learn more?
(Other definitions for temporal that I've seen before include "Passing" , "Earthly" , "Not eternal" , "Relating to time" , "Of wordly affairs, not spiritual" .)
