Animal sanctuary for a shark? No problem (5,3)
I believe the answer is:
noahs ark
'animal sanctuary' is the definition.
The definition suggests a singular noun which matches the answer.
'a shark? no problem' is the wordplay.
'problem' indicates an anagram.
'a'+'shark'+'no'='asharkno'
'asharkno' is an anagram of 'NOAHS ARK'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for noahs ark that I've seen before include "Rescue vessel" , "Great biblical boat" , "Biblical transport" , "animal transport" , "Hebrew patriarch's vessel" .)
