1. Dutch origin: The most common theory is that "splurge" comes from the Dutch word "splugen", meaning "to splash, to sputter, to gush forth". This would make sense, as "splurge" implies a sudden and excessive outburst, like water splashing.
2. Onomatopoeic origin: Another possibility is that "splurge" is onomatopoeic, meaning it imitates the sound of something splashing or bursting.
3. 19th-century slang: Some sources suggest that "splurge" first appeared as slang in the 19th century, possibly referring to a sudden and showy display of wealth or extravagance.
4. Uncertain origin: Despite the theories, the exact origin of "splurge" is still uncertain. There's no definitive evidence to support any one theory.
Regardless of its precise origin, "splurge" has been used in English since the late 19th century and has become a common word for indulging in something extravagant or excessive.
