On Sunday the two take a break from study (4)
I believe the answer is:
swot
'study' is the definition.
(I know that swot is a type of study)
'on sunday the two take a break from' is the wordplay.
'on' says to put letters next to each other.
'sunday' becomes 's'.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'take' indicates named letters should be taken away.
'a break from' becomes 't' (I am not sure about this - if you are sure you should believe this answer much more).
'two' with 't' removed is 'wo'.
's' next to 'wo' is 'swo'.
'swo'+'t'='SWOT'
Can you help me to learn more?
(Other definitions for swot that I've seen before include "Intensive studier" , "Person who studies hard" , "Cram for exam" , "One studying a lot" , "Mug up" .)
