+Ekin Gören sinwasse looks good
kúnasse? might work
mahtana as in “controlled”? perhaps, but could be misunderstood for other meanings of mahta-

blame: “put sin on someone”? of course “put” in itself is unattedted

As a single-word synonym for “blame” (substantival), an abstract noun that means “causerness, causership” (derived from KYAR), in place of Qe. káma ? As the verb, in a non-poetic context, one could use a longer expression such as namë/esta/savë X tyarindo/tyarmo or the attestation https://eldamo.org/content/words/word-4114972767.html (or its frequentative).

+ܤܡܝ ܦܠܕܢܝܘܤ oh I like the association with_leptenta-_

Would that be *leptetenta-?

+James Coish possibly - we have no examples of frequentatives formed from derived verbs as far as I know, so it’s a guess.

From the noun “shame” I arrived at the dilemma how to say “it’s a pity, it’s a shame [that sg happened/is]”.
One could say ma(nen) nainálima “how lamentable”, but perhaps there’ll be other ideas.

ma laherenya “how unfortunate”?

+Tamas Ferencz How to say then “Shame on me (you, him..)”?)

+Andre Polykanine no idea (yet). It’s quite idiomatic, isn’t it. na kúna? “Be bent”?

+Tamas Ferencz haahaahaa!
