Oh? I’m doing lidar; always interested to hear how related fields approach things.
The problem is, in engineering terms, the signal-to-noise ratio. Given a certain rate of lexical replacement and irregular change, there is a time period beyond which there is simply not enough signal to compare languages reliably.it saddens me that comparativists can't work with noisy (a.k.a. dodgy) data.
One can work with quite low signal-to-noise ratios. I've seen angle tracking demonstrated down to −30dB; the practical problem there is knowing that one is still tracking something,. One ought to be able to work with a set of alleged cognates where 75% are not.
Exactly. There is a limit to the comparative method: it eventually runs out of cognates, or rather, the cognate sets multiply and shrink the deeper you look, until each set consists of only one word, at which point it becomes indistinguishable from chance resemblance. The limit of detectability of a relationship is perhaps about 10,000 or 15,000 years; Afroasiatic gets close to this limit (there are currently two major reconstructions of Proto-AA, which disagree in many points and therefore cannot both be correct, which likely means that both are at least in parts wrong), and Mitian perhaps lies narrowly within this limit, too. It is a bit like C14 dating, which cannot date samples more than about 50,000 years old because beyond that age, there is no measurable quantity of C14 left in the sample.
The problem is that it’s not 75%: it can easily be more like 95% non-cognate or more. Also, unlike the case you mention, you don’t necessarily know if they are cognate in the first place — indeed that’s precisely the thing you’re trying to prove.Richard W wrote: ↑Tue Sep 01, 2026 9:13 amOne can work with quite low signal-to-noise ratios.

Well, it shouldn't be. You should be asking whether there are cognates (sensu stricto) there. The answer will generally be probabilistic.
Does the AA 1st person pronoun *ˀan-Vk- (Semitic *ˀanāku) have a Mitian counterpart?Richard W wrote: ↑Tue Sep 01, 2026 8:16 amYou can always look at relating PIE and Afroasiatic (AA) as a prelude to relating Mitian to AA. As someone who is professionally used to work with noisy data (specifically from radar), it saddens me that comparativists can't work with noisy (a.k.a. dodgy) data.

Proving two words are cognate can be difficult. One can be uncertain because of divergences in meaning, and sporadic or highly conditional sound changes can be difficult to confirm when the material is slight. Conversely, there are cases where the semantic and
This may just be a case of over-summarization, but you seem to forget that the comparative method is iterative. It doesn't matter that proposed cognates are uncertain; that's only the first step. You look for regular sound changes, and if you find them, you revise the cognate list to reflect what you find.Richard W wrote: ↑Tue Sep 01, 2026 5:52 pm Proving two words are cognate can be difficult.

phonetic correspondences are good, e.g. English and Farsi bad or, without any plausible common ancestor, English and Mbabaram dog. Making a yes or no decision is not a useful approach when any actual matches have been buffeted by the millennia.

Yep. The sound correspondences that are often proposed are mostly trivial - each PIE phoneme corresponds to the closest PU phoneme. That's not what to expect from two languages that had parted ways thousands of years ago, but from loanwords. The pronouns, however, are another matter. Pronouns can be borrowed, but the borrowing of a whole paradigm of them seems less likely.Travis B. wrote: ↑Tue Sep 01, 2026 7:44 pm It also should be noted that sound correspondences across different groups that seem too close are very, very often loans. Take IE and Uralic, for instance ─ most apparent 'cognates' are, when you look closer, obvious loans, especially since very many of these are clearly not from PIE into PU, but rather are from PII into PU. Real cognates usually reflect systematic sound changes from a common ancestor, not superficial similarity.
I also believe that the noun paradigms (or at least Nominative, Accusative, and Ablative, along with Dual and Plural) are shared.

Actually, yes you can. The most famous case is Kupwar but there are many others.Brilliant-Resource14 wrote: ↑Wed Sep 02, 2026 6:01 am You don't just sprachbund all of your damn grammar
But if looking for 2 or 3 of the 3 to be so, you get 90%.zompist wrote: ↑Tue Sep 01, 2026 6:32 pm (Now, maybe it would be useful to attach a probability to each asterisk. That is, a reconstruction like PIE is, say, 50% probable in its details. Then a reconstruction based on other reconstructions, like Nostratic, is 25% probable or less. People forget how fast multiplying probabilities reduces the overall certainty level. Chain together 3 statements of 80% probability and the result is just 51% probable.)
That is called metatypy. It has been quite some time since I read about the Kupwar case, but what I remember is that the languages of Kupwar have syntactic structures that almost perfectly match morpheme by morpheme, but the sound shapes of the morphemes did not converge - Kupwar Marathi still has Indo-Aryan morphemes, Kupwar Kannada still has Dravidian morphemes. What we have in IE and Uralic is the opposite: the structures are quite different (IE is fusional with ablaut, while Uralic is agglutinating with vowel harmony), but the morphemes have similar sound shapes. This suggests that the languages are related, but one (or both) of them was heavily restructured, perhaps by a substratum with a different structure. And as Uralic looks more "typically Mitian" than IE (e.g., Turkic or Eskimo-Aleut appear to have typologically more in common with Uralic than with IE) and generally has a more archaic look and feel, it seems likely that it was PIE which was restructured.bradrn wrote: ↑Wed Sep 02, 2026 6:03 amActually, yes you can.

Yes, and that is the usual situation with metatypy — for another example see e.g. https://web.archive.org/web/20070703083 ... tatypy.pdf.It has been quite some time since I read about the Kupwar case, but what I remember is that the languages of Kupwar have syntactic structures that almost perfectly match morpheme by morpheme, but the sound shapes of the morphemes did not converge - Kupwar Marathi still has Indo-Aryan morphemes, Kupwar Kannada still has Dravidian morphemes.
