UK

UK is a Primitive Quendian root signifying "nasty". Patrick H. Wynne notes that the root is "apparently an onomatopoeic stem" and that it is "probably related to the root UG 'dislike' (whence Q. úra 'nasty')".

In Eldarin Roots and Stems appear the roots "? UK, UKLA" (without any given significations, except for being one of the opposites of AYA). It has been suggested that "the queried stem uk in this note is perhaps the same as later UK 'nasty'".
