Meagre, scant (6)
I believe the answer is:
paltry
I believe this clue is a double definition.
'meagre' is the first definition.
(similar in meaning)
'scant' is the second definition.
(thesaurus)
(Other definitions for paltry that I've seen before include "Small and mean" , "Feeble" , "Petty - worthless" , "Trivial or contemptible" , "Insignificant, trifling" .)
