Ooooh yes, please keep these coming

Alternative reconstructions: *ésh₂r̥, *h₁ḗsh₂r̥

The first one smells weird; PIE roots are typically triconsonantal and start with a consonant. That ending *-r̥ looks more like a suffix than part of the root itself.

*h₁ḗsh₂r̥ vs. *h₁ésh₂r̥ in the meantime looks like ablaut between lengthened and full grades, but it’s hard to rely on Hittite for that - the plene spelling might be there not to indicate a hypothetically long vowel, but for the descendant of that *h₁. (Probably [h] or [ʔ].)
