"Blend of Scott and Lynn"
The name Scottlynn is commonly a female name.
Scottlynn is a modern American blend of the given names Scott and Lynn, joined into a single name. It first appears in United States birth records in 2001, which fits a late twentieth-century formation rather than an older tradition. Both elements are long established in English-language naming: Scott comes from the Old English Scottas, the name for the Gaels, and Lynn is a Welsh-derived surname from llyn, meaning lake.
The pronunciation of Scottlynn is SKOT-lin.
