Clear European vote in line with law, under pressure (8)
I believe the answer is:
explicit
'clear' is the definition.
(I've seen this before)
'european vote in line with law under pressure' is the wordplay.
I cannot really understand how this works, but
'european' could be 'e' (abbreviation e.g. EU) and 'e' is found in the answer.
'vote' could be 'x' (how votes are marked) and 'x' is located in the answer.
'line' could be 'l' (used when specifying particular lines from a poem) and 'l' is found in the answer.
'pressure' could be 'p' (abbreviation) and 'p' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for explicit that I've seen before include "Leaving no room for doubt" , "Clear and plain in language" , "Express - precise" , "Fully stated" , "Precise - outspoken" .)
