Groped around for cable (4)
I believe the answer is:
rope
'cable' is the definition.
(thesaurus)
'groped around' is the wordplay.
'around' indicates a hidden word.
'ROPE' is hidden in the letters of 'groped'.
'for' is the link.
(Other definitions for rope that I've seen before include "Lasso?" , "making money easily when old?" , "Length of material used to tie or secure things" , "Stranded fastener" , "Cable, cord, hawser" .)
