From Proto-Indo-European *h₁erm- (“poor, ill”). Cognate with Hittite 𒅕𒈠𒀭 (erman, “sickness”). (Can this(+) etymology be sourced?)
Alternatively, from Pre-Germanic *h₃orbʰmos, with loss of -b- before -m-, from Proto-Indo-European *h₃erbʰ-, whence English orphan. Compare the Norse variant aumr, as from *arbmaz with no loss of -b-, which mirrors the dissimilation of Old Norse haustr from *harbistaz.[2]
*armaz (comparative *armōzô, superlative *armōstaz)[2]
