"mean, worthless, despicable," 1560s, probably an adjectival use of noun paltry "worthless thing" (1550s), associated with dialectal palt, pelt "trash," cognate with Middle Low German and East Frisian palte "rag," Middle Dutch palt "broken or torn fragment." Similar formation in Low German paltrig "rubbishy," East Frisian palterig "ragged, torn."
