Latin satellēs 'bodyguard'

Latin satellēs 'bodyguard', whose accusative satellite- was borrowed into French satellite, is a loanword from Etruscan zatlaθ 'axe-bearer', from zaθ, zat 'axe'¹. I think likely a connection with IE *h4adhes- 'axe, adze' (Hittite ates, atessa-, English adze, Latin assis, asser).

This formation is parallel to the theonym Raθlθ 'Stick-carrier', from raθ 'stick'², possibly related to IE *wraHd- 'root, branch' > Latin rādix 'root', a Wanderwort also found in Afrasian *rVhVt’- 'branch, rafter' (Semitic, Berber) and Georgian rt’o 'branch, bough'. Latin rāmus 'branch, bunch' < *wrād-mo- is cognate to Greek rhádamnos 'branch, twig', a Pre-Greek substrate loanword also found as rhódamnos, oródamnos.

¹ Etruscan z stands for /ts/.

² Latin ratis 'rafter' must be an Etruscan loanword.

Occitan darbon 'mole'

Rhaeto-Romance karmún 'weasel'

Following Meyer-Lübke (REW 1700), the French linguist Xavier Delamarre¹ proposes Gaulish *karmon- as the source of Rhaeto-Romance (Surselvan) karmún 'weasel', although personally I think the source language would be Italoid.

This is a regional IE word *k´ormon- 'weasel, ermine' found in OHG harmo, Lithuanian šarmuõ 'wildcat, ermine', šermuõ 'weasel, ermine' as well as Basque armindderi (Aezk), armonddegi (HN), ergoniri (HN), ergoneri (HN), ergenore (HN), erbindori (*L), erminori (HN), erbiñore (G), erbiñude (G), erbiñure (G, L) 'weasel' (a compound whose second member is unknown²), with loss of the initial stop due to Martinet’s Law.

Probably related is Mongolian *keremü 'squirrel', borrowed into Tungus keremun (MT 123)³. There’re also Turkic *Küŕen, Mongolian *kürene 'ferret, weasel' (EDAL 1105) and Tungusic *gurma- / *gurna- 'hare; squirrel; ermine' (EDAL 572), wrongly linked to different words in other Altaic languages⁴.

² The forms erbi-unide (Bazt), erbionide (HN) are the product of a folk etymology from erbi 'hare' and unide 'wetnurse'.

⁴ In fact, the latter is absurdly paired to Turkic and Korean words meaning 'antelope; deer'.
