Unemployed, one gets led astray (4)
I believe the answer is:
idle
'unemployed' is the definition.
(similar in meaning)
'one gets led astray' is the wordplay.
'one' becomes 'I' (Roman numeral).
'gets' says to put letters next to each other.
'astray' indicates an anagram.
'led' is an anagram of 'dle'.
'i'+'dle'='IDLE'
(Other definitions for idle that I've seen before include "Turn over" , "staying in bed all day?" , "Good-for-nothing" , "Lazy, doing nothing" , "Lazy - vain" .)
