Apparently where trap is centrepiece in terrorist attack (2,3,4,2,2)
I believe the answer is:
on the face of it
'apparently' is the definition.
(synonyms)
'trap is centrepiece in terrorist attack' is the wordplay.
I cannot really see how this works, but
'attack' could be 'fit' (fit is a kind of attack) and 'fit' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'where' acts as a link.
Can you help me to learn more?
(Other definitions for on the face of it that I've seen before include "at a quick glance" , "Where over mountain one might see climber" , "At first glance (2,3,4,2,2)" , "Where you can see clock's hands" , "Apparently (2,3,4,2,2)" .)
