Bitter or pearl; woman from Magdala
Matalyn is a modern American creative spelling. It most likely functions as a blend of Madeline, meaning 'woman from Magdala,' and the name Madelyn, or potentially a variation of the name Mattea or Margaret. As a contemporary invention, it lacks a singular ancient root but carries the phonetic appeal of popular 'lyn' endings.
