Lingers idly with hard toilers (7)
I believe the answer is:
loiters
'lingers idly' is the definition.
'loiters' can be an answer for 'lingers' ('loiter' can be a synonym of 'linger'). I am not sure about the 'idly' bit.
'hard toilers' is the wordplay.
'hard' indicates an anagram.
'toilers' anagrammed gives 'LOITERS'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for loiters that I've seen before include "Hangs about with toilers" , "Hangs about idly" , "dawdles" , "Hangs around" , "Fails to move on" .)
