Riffle
A name most likely linked to a riffle—a shallow, rapid stretch of water in a stream.
The #6,253 most common surname in the United States (2010 Census) — about 1 in every 56,536 Americans shares it.
Etymology
Riffle is best understood as an English topographic surname from the common noun riffle, meaning a shallow, broken, or rapid part of a stream. The word is related to the idea of water rippling or running over stones, and in surname use it would have identified someone who lived near such a place. Because the historical excerpt only lists the word among water-landscape terms and does not explain the surname directly, this is a careful inference rather than a fully documented dictionary derivation.
History
As a surname, Riffle appears in English-speaking records and is especially familiar in the United States. It likely arose independently in more than one place wherever local speech used riffle for a stretch of rough, shallow water. The name is relatively uncommon but stable in modern American usage.
