Foreigners giving misinformation in answer (6)
I believe the answer is:
aliens
'foreigners' is the definition.
('alien' can be a synonym of 'foreigner')
'misinformation in answer' is the wordplay.
'misinformation' becomes 'lie' (lies are false information).
'in' means one lot of letters goes inside another.
'answer' becomes 'ans' (abbreviation for answer).
'lie' inserted into 'ans' is 'ALIENS'.
'giving' acts as a link.
(Other definitions for aliens that I've seen before include "Foreigners or creatures from outer space" , "Forms of life assumed to exist outside Earth" , "Outsiders" , "'Little green men'?" , "Beings from another planet" .)
