Lake or lime tree
Lynia is likely a modern elaboration of the name Lynn or a variation of the Welsh name Linna. It is often associated with the Welsh word for lake or the Germanic root for the linden tree. As a rare choice, it offers a melodic, multi-syllabic alternative to shorter nature-inspired names.
