Everything in the typescript conservative? It’s rather difficult to believe (4,5)
I believe the answer is:
tall story
'it's rather difficult to believe' is the definition.
(a tall story is hard to believe)
'everything in the typescript conservative?' is the wordplay.
'everything' becomes 'all' (all things).
'in' means one lot of letters goes inside another.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'typescript conservative?' becomes 'story' (I can't justify this - if you can you should give a lot more credence to this answer).
't'+'story'='tstory'
'all' inserted inside 'tstory' is 'TALL STORY'.
Can you help me to learn more?
(Other definitions for tall story that I've seen before include "Incredible account" , "Unbelievable yarn" , "suggesting Jack and the Beanstalk?" , "Unlikely tale" , "unreliable account" .)
