여섯

Etymology
🇨🇬 demonstrates that the immediate pre-fifteenth century form was *ᄋᆢᄉᆞᆺ or *ᄋᆢ슷. The Seoul dialect underlying the Middle Korean corpus had a merger of and  which was still relatively recent by the invention of the alphabet in the 1440s. Beyond this, the ultimate reconstruction of the ancestral Koreanic root for "six" is difficult. See a list of relevant attestations and forms in Appendix:Historical Koreanic numerals.
