Lots thrown into hole (4)
I believe the answer is:
slot
'hole' is the definition.
(thesaurus)
'lots thrown' is the wordplay.
'thrown' indicates an anagram.
'lots' is an anagram of 'SLOT'.
'into' is the link.
(Other definitions for slot that I've seen before include "Lots (anag.)" , "Hole for money" , "Opening (for coins)" , "Small opening, for a coin say" , "This gaming machine operates by insertion of coin" .)
