apamitya

 In Sanskrit, apamitya most commonly means “a debt”, though in Vedic usage it can also mean “something to be thrown away.”

Summary

apamitya has two attested senses:

1. Debt, obligation, something owed (the standard classical meaning).
2. Something to be thrown away (older Vedic meaning).

If you want, I can also explain how the term is used in Vedic ritual texts or how it relates to ṛṇa (“debt”).
