European Union almost provided backing? It's unclear (5)
I believe the answer is:
vague
'unclear' is the definition.
(I've seen this before)
'european union almost provided backing? it's' is the wordplay.
'european union' becomes 'eu'.
'almost' means to remove the first letter.
'provided' becomes 'gav' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'backing?' shows that the letters should be reversed in order (I've seen 'backing' mean this).
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'eu' with its initial letter removed is 'u'.
'u'+'gav'='ugav'
'ugav' in reverse letter order is 'vagu'.
'vagu'+'e'='VAGUE'
Can you help me to learn more?
(Other definitions for vague that I've seen before include "Nebulous" , "Blurred" , "Hazy" , "Indefinite" , "Rough" .)
