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' acts as a 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" .)
