We're all familiar with the words anonymous, synonymous, and eponymous, which are all to do with names. I came across allonymous in the OED today (published or appearing under the name of someone other than the real author), and it prompted me to look up other 'onymous' words.
The suffix onymous is also a word in its own right; it means 'having a name, bearing the name of an author'. There are a few other interesting 'onymous' words:
cryptonymous: characterised by a pseudonym or code name
euonymous: well or felicitously named
paronymous: derived from the same root, cognate
polyonymous: having many names or titles
pseudeponymous: that is falsely named or attributed
There's also the word tecnonymous, which the OED defines, not very helpfully, as 'practising tecnonymy'. And tecnonymy is 'the practice of naming a parent from his or her child' (so, you'd be known as 'father of So-and-so' or 'mother of So-and-so' -- I must admit that I have often referred to myself as 'mother of ...' to teachers and other parents when introducing myself, as they know my children already).
There are several rare words beginning tecno- in the OED that are all to do with children, since tecno- comes from the Greek word for 'child' (words beginning paed- are more common in English - and that's a Latin prefix). There's tecnotonia (infanticide), tecnogonia (the age of a father at his eldest child's birth, or it can also mean 'child-bearing'), tecnolater(or teknolater) (one who worships children) and tecnology (the scientific study of children).
