Celtic *koret- 'palisade'

A palisade

Celtic *koret- 'palisade' (Middle Irish cora, Middle Welsh cored, Old Breton coret)'¹ has been linked by some Indo-Europeanists to Germanic *xurdí-/*xúrθi- and Latin crātis 'hurdle'², from an IE protoform whose meaning can be reconstructed as 'to weave'. 

A hurdle

However, IMHO this etymology is semantically unsatisfactory, as hurdles were traditionally made from wattle (woven split branches), while palisades are made from stakes planted vertically on the ground. This is why I'd prefer to derive the Celtic word from a different protoform *s-korHt- 'twig, pole' found in Baltic (Lithuanian kártis 'think stick, latte, stake', Latvian kãrts 'rod; a measure of length') and Germanic (Old Norse skorδa 'support, rod') ,in a pars pro toto etymology.
