Etymology

gratis = grat<thanks> + is<adverbial suffix>

  • grat (from Latin grātia meaning "favor, thanks")
  • is (adverbial suffix in Latin, indicating manner or condition)

Etymology Origin:
The word gratis originates from Latin grātīs, the ablative plural form of grātia ("favor, kindness"). It originally meant "as a favor" or "out of kindness," implying something given without expectation of payment. Over time, it evolved into English to explicitly denote "free of charge," retaining its Latin spelling and structure. The morpheme grat reflects the core idea of gratitude or favor, while -is marks its adverbial function.
