Proto-Nakh: *ʔārcV
Meaning: 1 bar, bolt, cross-beam 2 purlin
Chechen: orcχa 1
Ingush: ɔrc 2
Comments: Chech. orcχa is a development < *ʔārcu-ḳa (with a variant *-ḳa of the PN diminutive suffix *-ḳ). Length of vowel is determined on basis of Ing. ɔrc (reflecting *ʔārcu - probably the original oblique base in the paradigm *ʔārc, *ʔārcu-). 6th class in both languages.
The same root is present in the PN compound *duq̇-ārc 'stick for locking the yoke (*duq̇)' > Chech. duq̇arc, Ing. duq̇ɔrc.
