Zaylin
Zaylin Origin and Meaning
Newly coined options, the letter Z, and strong A sounds all remain on trend for boys in the US and Zaylin ticks all the boxes. Like a mash up of Zaiden, Zayn and Waylon, Zaylin was given to around 70 boys in 2023. It is the second most popular spelling of the name, above Zaylan and Zaylon, but not so well used as Zaylen.
As it is a modern invention, the meaning of Zaylen is hard to to pin down, but if you break the name down, you've got some options. Zay could come from Xavier/Zavier meaning "new house", from Zayn or Zayne meaning "beauty" and "God is gracious" respectively, or from Zayd, meaning "to increase".
Meanwhile, len might link to the Irish diminutive meaning "little" or from the English suffixes lan/lon/len meaning "land". You can play about with these to make meanings such as "new house on the land" or "little beauty", though none can be given as the definitive meaning.
