In anatomy, heterochromia refers to a difference in coloration, usually of the iris but also of hair or skin. Heterochromia is a result of the relative excess or lack of melanin (a pigment). It may be inherited, or caused by genetic mosaicism, disease, or injury.

Heterochromia of the eye (heterochromia iridis or heterochromia iridum; the common wrong form "heterochromia iridium" is not correct Latin) is of two kinds. In complete heterochromia, one iris is a different color from the other. In partial heterochromia or sectoral heterochromia, part of one iris is a different color from its remainder.
Eye color, specifically the color of the irises, is determined primarily by the concentration and distribution of melanin. The affected eye may be hyperpigmented (hyperchromic) or hypopigmented (hypochromic). In humans, usually, an excess of melanin indicates hyperplasia of the iris tissues, whereas a lack of melanin indicates hypoplasia. (definition from Wikipedia)
Propinquity is a noun
meaning nearness in place or time or relationship; kinship; similarity in
nature. In social psychology, propinquity is one of the main factors leading to interpersonal attraction. It refers to the physical or psychological proximity between people. Propinquity can mean physical proximity, a kinship between people, or a similarity in nature between things ("like-attracts-like"). Two people living on the same floor of a building, for example, have a higher propinquity than those living on different floors, just as two people with similar political beliefs possess a higher propinquity than those whose beliefs strongly differ.
So those who have a mutual interest in words and their meanings have a higher propinquity than exists between those who are interested and those who are not.
Monica recently bought a rucksack that was described on its wonderful label as 'indefectible'. Hwne I saw that I assumed it was one of those made-up words that translators occasionally manage to create from a mangle of similar words. I was wrong. It is a real word.
Indefectible adj. - Having the ability to resist
decay or failure; lasting; having no flaw or defect; perfect.
I just wish I were indefectible!
In a religious context the indefectibility of the Church is a gift
from Christ to the Church by which she is preserved to the end of the age as
the "institution of salvation".
My daughter Helen commented in November 2008 in her Blog that she was now keeping a notebook of new words that she came across during her reading. "This week I bought a lovely little leather bound book to write new words in as I read them . I've added a few from "1984", but my favourite has to be persiflage (from the French persifler) which means banter." I later discovered that my older daughter, Bryony, also kept a similar notebook.
This inspired me to create a Word blog. This will include both new words, favourite words and the origins of phrases that we commonly use. A definition and some comment, perhaps even a relevant quotation, will acompany the word or phrase.

I'm a blogger - nowadays that seems to be my main occupation and Rambles from My Chair is my main blog. I’m a retired local government executive - now studying how to survive a neurological disorder that gives me various problems but, hopefully, a whole new outlook on life and an increased sense of humour and perspective. I enjoy all manner of communication apart from the telephone and am constantly e-mailing, texting, writing postcards and letters and commenting on other people's blogs.
