Supplanter; combination of Jace and Lynn
Jacelyn is a modern American invention, likely created by blending the masculine Jace with the popular feminine suffix -lyn. As a derivative of Jace (and therefore Jacob), it carries the etymological meaning of 'supplanter' or 'held by the heel.' It emerged in the late 20th century as part of the trend for rhythmic, multi-syllabic names ending in 'lyn'.
