K. Reshetnikov's notes:It is probable that Lap. *c'orэk 'small reindeer herd' (Lehtiranta 26) should also be regarded as belonging to this etymon (with a metathesis *c'okэr > *c'orэk, which makes the comparison somewhat questionable; on the other hand, at present we are unable to suggest any alternative etymology for this Lap. word).
