Current and potentially endless obstacle to Labour (8)
I believe the answer is:
idleness
'obstacle to labour' is the definition.
I can't tell whether this definition defines the answer.
'current and potentially endless' is the wordplay.
'current' becomes 'I' (symbol for electric current).
'and' says to put letters next to each other.
'potentially' is an anagram indicator (letters have the potential to spell a new word).
'endless' is an anagram of 'dleness'.
'i'+'dleness'='IDLENESS'
Can you help me to learn more?
(Other definitions for idleness that I've seen before include "State of inactivity" , "Disinclination to work" , "Laziness" , "Inactivity, indolence" , "I'm having nothing to do" .)
