Information in British paper is correct (3)
I believe the answer is:
fit
'is correct' is the definition.
(thesaurus)
'information in british paper' is the wordplay.
'information' becomes 'i' (common abbreviation for information).
'in' indicates putting letters inside.
'british paper' becomes 'ft' (newspaper the FT, Financial Times. I am not sure about the 'british' bit.).
'i' inserted inside 'ft' is 'FIT'.
Can you help me to learn more?
(Other definitions for fit that I've seen before include "Suitable; sudden attack" , "Attractive" , "Sound in body or suitable" , "Apt" , "Healthy; spasm" .)
