  • Then there are the stupid almost-tautonyms like Gekko gecko, the tokay gecko (named after its cry). I mean, why??

    By the way, in response to a certain leather-eared marsupial's implied criticism about people on Wordie "putting on linguistic airs and graces", I have just one rejoiner:

  • hotshots as a compound of hots + hots is nonsensical in common usage. I can't see or hear it as a tautonym on that basis. As rollie says, the quizfiends can please themselves but it seems very cheesy when they want to put on linguistic airs and graces.

  • Since "hotshots" is also composed of "hots" + "hots", it is a tautonym.

  • For puzzling purposes, games and fun, people can do whatever they like.

    My real objection to Mr. Cole's use of "tautonym" is that it goes against my sense of what a word is, and what makes a word. Words are only superficially composed of letters. A word like "hotshots" might be just as well written "hotšots" (Slovene transliteration) or хотшот�? (Russian transliteration) – but not "ho�?oc" or "хочоц", which violate the word's structure – and the imagined tautonymy instantly evaporates. Words are, essentially, composed of morphemes and phonemes, and it is with respect to these that the established understanding of tautonymy (a name based on repetition) applies.

    But it was very nice of you, oroboros, to take the trouble to ask the source, and of Mr. Cole to reply.

  • To rolig: I'm sure Chris Cole is aware of the pro forma definition of tautonym but has widened its parameters to include repeated letters for the purposes of his wordplay opus. Here is his reply via email to me:

    Actually the Webster's Third definition of "tautonym" applies only to taxonomic names, so we're free to generalize it as we choose when applying it to logology. My use of the word conforms to the National Puzzlers' League's usage and besides it's more fun to find words like "hotshots."

  • There are two main kinds of tautonyms in zoology. In an "absolute tautonym", the genus and specific name are identical (e.g., Gorilla gorilla). In a "virtual tautonym", the names are similar in spelling, derivation, or meaning. The International Code of Zoological Nomenclature give several examples: Bos taurus, Equus caballus, Ovis aries, Scomber scombrus, Sphaerostoma globiporum, and Spinicapitichthys spiniceps.

  • I'm afraid Chris Cole is wrong. A tautonym is a name that is composed of identical parts. Since "hotshots" is composed of "hot" + "shots", it is not a tautonym. In biology, a tautonym is a taxonym where the genus name and the species name are the same, as with the corn crake, Crex crex. In everyday life, names like "Pop-Pop" (what I used to call my grandfather) and "John-John" (what JFK Jr. was called as a child) are tautonyms.

  • A word formed by repeating a sequence of letters: hotshots.
