Usage notes

 * The particle is attached to, , , and , and with certain adverbs or nouns referring to place, direction, or means. Historically, it could also combine with , but this is now fully obsolete.

Etymology 2
The Cheoyong-ga is claimed to be from the ninth century but is almost certainly of much later provenance, possibly as late as the thirteenth century. Not attested in earlier Old Korean sources.

Further etymology unclear. In 13th century  texts, this suffix appears as when fused with the honorific suffix. This suggests that it is a compound of +  +.

However this is incompatible with the tonal pattern, as the syllable 다 has low pitch rather than the high pitch expected from this etymology. Perhaps the pitch was affected by that of the particle, although Kim Seong-gyu rejects this possibility.
