Author in Hanoi's Premier Hotel worked out pi (6-4-4)
I believe the answer is:
holier-than-thou
'author in hanoi's premier hotel worked out pi' is the definition.
I can't tell whether this defines the answer.
'author in hanoi's premier hotel worked out' is the wordplay.
'premier' suggests taking the first letters.
'worked out' indicates anagramming the letters.
The initial letter of 'hanoi' is 'h'.
'author'+'in'+'h'+'hotel'='authorinhhotel'
'authorinhhotel' anagrammed gives 'HOLIER-THAN-THOU'.
Can you help me to learn more?
(Other definitions for holier-than-thou that I've seen before include "Sanctimonious" , "Self-righteous" .)
