I enjoy pattern recognition. I like to classify, categorize things and develop frameworks. That possibly explains my fascination with lists. This is an effort to list words ending in -onym, words that describe names.
Acronym: a word formed from the initial letter or letters of each of the successive parts or major parts of a compound term. My first encounter with an acronym that I can remember is
RADAR (2nd year Engineering class at IIT)
Allonym: the name of a person, usually a historical person, assumed by a writer. Lal Mohan Ganguly, a character in Satyajit Ray’s Feluda stories, writes under the name of
Jatayu, a character from the Indian epic
Ramayana.
Antonym: a word of opposite meaning. My parents told me later that when I was a child and our house was being built, I used to pick up a brick and say, "the brick is heavy light," thinking heavy is a qualifier to the degree of lightness and not realizing that it exactly means the opposite of light.
Ananym: a name formed by reversing letters of another name, often used as a pseudonym. My niece’s name is Sayani but her sign-in name is InaYa$. I didn’t figure the logic till I learned that Oprah’s production company is called Harpo. The light bulb went on.
Anacronym: a word whose origin as an abbreviation is no longer widely known. Most people don’t remember what the letters stand for. e.g. scuba, laser, etc.

face the music
Anonym: a fictitious name used when the person performs a particular social role. Stage name for an actor, a pen name for an author.
Anepronym: a word that becomes so well established that it is used to define other objects that share its own definition e.g. Xerox for photocopy or FedEx for express delivery
Anthroponym: the name of human beings. Patronym, Teknonym, Ethnonym (autonym, endonym, exonym) belongs to the category.
Apronym: is an acronym/bacronym which is also a real word e.g.
SAD stands for Social Affective Disorder.

Autantonym: a word with many meanings, one of which is defined as the reverse of one of its other meanings. e.g. overlook can mean ‘to inspect’ or ‘to fail to notice’. cleave can mean ‘stick together’ or ‘split apart’. This type of word is also known as Contronym or Contranym or Antagonym. A good list is available
here.
Autonym: a person's own name, as distinguished from a pseudonym. A word that describes itself. e.g. Abbr. is an abbreviation.
Basionym: the first name published for a biological taxon (species, genus, etc.), which remains the defining name for the taxon even when the taxon has been transferred to a new name
Backronym: (from back+acronym) a word re-interpreted as an acronym e.g. PERL. Taking a word that already exists and coming up with a humorous phrase using the letters of the word as initials. My favorite is

I used to draw and paint growing up. Somewhere on the way, I lost that gift. I made another attempt between 1993 and 1996; sold few during auctions for charities but then stopped again due to workload and work-life imbalance.
