Per Rix (LIV) and Vasmer, possibly related to *reťi(“to speak, to say”), from Proto-Indo-European*rek-. If so, cognate with Sanskritरचयति(racáyati, “to make, to form, to correct”). Vasmer adds Gothic𐍂𐌰𐌷𐌽𐌾𐌰𐌽(rahnjan, “count”) as an additional cognate. Rix reconstructs the PIE etymon of this verb as iterative *rōk-ye-.
Vaillant asserts that this verb is a borrowing from Proto-Germanic*rōkijaną(“to care about”), cf. Old Norserœkja; but Vasmer specifically denies this.
