Also short of rum, et cetera (3,2,5)
I believe the answer is:
and so forth
'et cetera' is the definition.
(thesaurus)
'also short of rum' is the wordplay.
'also' becomes 'and' (I've seen this before).
'rum' is an anagram indicator (rum can mean strange or unusual).
'short'+'of'='shortof'
'shortof' anagrammed gives 'soforth'.
'and'+'soforth'='AND SO FORTH'
(Other definitions for and so forth that I've seen before include "Along with other things" , "Et cetera" , "implies others of the same type" , "etc." , "imagine what follows" .)
