Usage notes
This form is used by the mainstream "' glossing tradition" of Interpretive, referring to all Korean-language glosses to the Buddhist canon up to 1300 except for two glosses of excerpts of the ' and a recently discovered gloss of the Sutra of the Repentance Ritual of Great Compassion, all three of which share idiosyncratic features including the use of what appears to be a graphic abbreviation of.

As with Middle and Modern Korean (see and ), the Old Korean  construction had two forms: a short form in which the adverb directly preceded the negated verb, and a long form in which the adverb negated the verb  similar to English do-support. However, unlike in Middle and Modern Korean, did not act as a true auxiliary verb, as the main verb was nominalized to become the direct object of.

According to the analysis of Mun Hyeon-su, when the main verb was modified by another adverb, word order in the long form construction of differed from the long form construction of :


 * Yogācārabhūmi-Śāstra tradition: [NOMINALIZED VERB] [ADVERB]
 * Avatamsaka Sutra tradition: [NOMINALIZED VERB] [ADVERB]
 * Middle and Modern Korean: [ADVERB] [MAIN VERB]

Reconstruction notes
The final phonogram denotes the coda consonant *-k.

This adverb is not attested in Middle Korean. However, some sixteenth-century Chinese-Korean glossaries for use by schoolchildren gloss the Chinese word as, of uncertain meaning. As this is the only known negative ending with *-k in Middle Korean sources and as the Middle Korean glossary genre is celebrated for linguistic archaisms, Old Korean is conventionally reconstructed as *ANTOk. This also matches and, which use the same logogram.
