Proto-Eskimo: *ăriɣV-
Meaning: to dig, to burrow, to scratch
Russian meaning: копать, рыть нору, скрести
Comments: This root is sometimes contaminated with *arɣa 'hand' due to close phonetic resemblance but should nevertheless be separated from it despite CED. More probable is the connection to Chukchee rǝɣ- 'to dig' < PCh *šǝɣ-, KCh *'ǝrŋ(u)-.
