Patriarch showing evident lack of surprise? (4)
I believe the answer is:
noah
'patriarch' is the definition.
(patriarch in the Bible)
'evident lack of surprise?' is the wordplay.
'evident' becomes 'no' (I am not sure about this - if you are sure you should believe this answer much more).
'lack of' means to remove the last letter (I've seen 'lacking' mean this (the word is incomplete or lacking)).
'surprise?' becomes 'aha' (I've seen this in another clue).
'aha' with its final letter taken away is 'ah'.
'no'+'ah'='NOAH'
'showing' is the link.
Can you help me to learn more?
(Other definitions for noah that I've seen before include "Biblical ark builder" , "Oh, an ark man" , "Patriarch of the Ark" , "Legendary Biblical boat-builder" , "Early boatman" .)
