'they collect' is the definition.
Although both the answer and 'collect' are nouns, they are not in the same form of the noun.

'there in rags sadly' is the wordplay.
'in' means one lot of letters goes inside another.
'sadly' indicates an anagram.
'rags' anagrammed gives 'gars'.
'there' going inside 'gars' is 'GATHERERS'.
