Description:

The modifier 'junikor' entered the Common language as the term 'junikoryn' as a straight borrowing of the English 'unicorn' from pop culture. 'Junikor' was originally a humorous back derivation with a sense like unique or special. Later Common speakers interpreted this as the primary meaning and the 'junikoryn' form as derived. 

Junikoryn still has the sense of a single horned horse but has the normal meaning of something unique, special and rare to the point of possibly not being real.

In a verb context, it is a pali verb and just means 'be a unicorn'.
