There are resemblances between some Mari words and items in other Uralic languages that are extremely blatant and yet, to my knowledge, have gone uncommented. That’s not to say that an etymological link is tenable, but one would expect the UEW or other general references to at least note and shoot down some prior attempt to relate the given words. Why have the following not been compared before, even in the heady early 20th century when standards were relatively lax?
- Finnish salama ‘lightning’ ~ MariE šolem ‘hail’. Yes, there’s a difference in meaning, but it’s not unusual for words denoting weather conditions to shift semantically, e.g. MariE jür ‘rain’ < Cv. yur ‘snow’. I suppose the difficulty here is that MariW šolem doesn’t show /a/ as some might have earlier expected in a word from *salama. However, it does agree with a formulation by Ante Aikio that Proto-Mari *o appears before *l if the word does not begin with a glide.
- Finnish pakkanen ‘frost’ ~ MariE W pokšə̑m ‘frost’
- Russian леньгас ‘loafer’, Estonian lõngus ‘lout’ ~ MariE laŋga ‘lazy’. Paul Ariste connected the first two in a 1966 paper, even mentioning some Finnish words, but he didn’t mention the Mari at all even though it’s there staring one in the face.
- MariE W paŋga ‘lump’ ~ Udmurt pog id. One would have thought the Mari would be included in the UEW (404) under *puŋka ‘Knollen, Beuele, Unebenheit’, as similar forms from across Uralic are listed there. MariE paŋga is in Paasonen’s dictionary, so it’s not like earlier researchers could have been unaware of this word. Even if one would prefer to see the Mari as a loan on account of its first-syllable *a, it’s curious that Bereczki didn’t include it in his 1992 list of Permian or Udmurt loanwords in Mari.
