오른손

Etymology
equivalent to, ultimately equivalent to a.

By the early twentieth century, the prestige Central dialect had mostly shifted to the innovative form. However, for unclear reasons, the older but now dialectal form was chosen as the Standard Korean form when the standardized variety was codified in the 1930s, rather than the Central form. In most other cases, Central forms were standardized even when innovative.

Perhaps because of this standardization and perhaps because of the influx of southern speakers into Central regions during South Korean industrialization, went into decline and is now not generally understood, even after it was belatedly added to the Standard Korean lexicon in the 1980s.
