You start to notice a lot of roots by applying a "toki pona" style phonetic rule: collapse all voiced and unvoiced consonants. Reverse Grimm's law. Th -> t. And then apply Arabic vowels: a, i, u. This is pretty much reversing the most common sound shifts over time. f=v=b=p, g=k, d=t, y=o=u, e=i. Cybernetics -> kupirnitics Government -> kupirnit It's probably also related to "operatus" (Latin for "work", things like cooperate and opera come from it) but I can't find sources. (co)operatus -> (k)upiratus Another example is the famous "father" etymology: Father/vader/pater -> patir (PIE *pH₂tér)

That doesn't seem plausible to me when you consider that opera is the plural of opus. Afaik in early latin, /s/ often went to /r/ when it fell between vowels. That is why it has /s/ in the nominative but /r/ when you start to inflect it with suffices. This happens a lot for third declension nouns where nominative ends in -s (opus is one such example) Other examples of this pattern: Corpus -> corporem (not *corpusem) Venus -> Venerem (not *Venusem) Flos -> florem (not *flosem) Colos -> colorem (not *colosem) Or more simply, we can look at opus and see it comes from a different PIE root from cyber. (When i look it up, the former has a root meaning "work", and the latter has a root meaning "turn")

  I was under the impression that the underlying /r/ became [s] in the nominative case where it was followed by an /s/, rather than -- as you seem to suggest -- an underlying /s/ becoming [r] when intervocalic.

    Intervocalic s > r (rhotacism [1]) is a well known phenomenon in early Latin. Any Latin grammar from the last 150 years should mention it. The comparative method proves the original phoneme was /s/ in many cases: generis - compare Greek gene(s)os, Sanskrit janasas jus, juris - compare justitia where the /s/ was not intervocalic robur (archaic robos), roboris - compare robustus The 3rd declension has many s-stems like these though there are some original r-stems also like jecur (< PIE jekwor, compare Greek hepar). 1. https://en.wikipedia.org/wiki/Rhotacism https://en.wikipedia.org/wiki/Rhotacism

How do you explain the prefixed form in Latin (co-operatus) corresponding to the root form in other languages? Opus/operis is a productive form on its own in Latin.
