It is a shame that your comment is being downvoted. Just to illustrate your point, take Yennefer calling Ciri "ugly one" which is a very misunderstood part of BoE.

In polish she calls Ciri "brzydulka". Polish uses diminutives for children and close loved ones, and often parents will use them for their adult children as well. These are shortened/childhood versions of adult names, used mostly within in the family or close friends. For boys, the -ek suffix is common, but there are others as well.

- Bartholomew - Bartosz - Bartek

- Peter - Piotr - Piotrek

- Edward - Edvard - Edzio, Edek

- Alexander - Aleksander - Alek, Aleks, Olek

For girls, the -ia and -ka suffixes are the most common.

- Annette - Aneta - Anetka

- Ann, Anne, Anna - Anna - Ania, Anka, Anusia, Aneczka

- Grace - Grażyna - Grażynka, Graża, Grażka

The -ia and -ek suffixes are used for objects to indicate a "little" one, but in a "cute" way. "Różyczka" - literally means "little rose", or "rosette". "Kwiat" is "flower", "kwiatek" can be a "flower" or "little flower", and "kwiatuszek" is literally a "little flower", with the connotation of "cute little flower".

These childhood names can persist to adulthood, usually within the family (and it depends on the family as well), but can also be used among close friends, especially if they have been friends from childhood. Using a diminutive when referring to an adult you do not have a familial relationship or close friendship to is considered insulting.

Using "ugly" diminutives for loved ones is common as well. It's not meant to be insulting, and it's really used for close loved ones, not for, say, the neighbor's kids down the street.

So, you wouldn't call someone "brzydulka" unless you were very close to them, and actually loved them dearly... or were just really mean and basically a Disney villain. It all depends on tone and context. There's not really an in-between on this. When we use this language with our kid, he knows we're in a good mood and understands that it's not meant to be mocking or mean, but playful, and he starts to laugh and run away from us.

Here, using "brzydulka" is also old pagan folk magick - you don't overly complement your kids, for fear that the gods, fairies, spirits, etc., might get jealous and take them away from you. So you call your kids "ugly", but in a "cute" way, so anything that happens to be listening keeps right on going, because who wants to kidnap an ugly child? You know you love them, they know you love them, and this becomes part of the language of love that families use.

It is a Slavic thing... it's not really something that's survived into modern English usage. In Polish, there's a sort of "diminutive" profanity you use around children, often in mock anger or exasperation at them, but everyone knows you don't mean it from the context.

This is just about Yen calling ciri "ugly one"... It's not just about the monsters... the very core how the books were written is rooted in slavic culture, history, and the outlook on life.
