-소

Korean

Etymology

Ultimately from Middle Korean ᄉᆞᇦ〯 (Yale: -sǒW-, object-honorific suffix), which gradually came to have an addressee-honoring meaning. Compare 오 (-o-), 옵 (-op-), from the same suffix and both now with addressee-honoring meaning.

First attested for the imperative mood in the late sixteenth century. It expanded to the declarative and interrogative moods in the eighteenth century. However, it is not clear if the two suffixes are related.

The early imperative suffix was invariably 소 (-so), as in modern Gyeongsang. There are many theories about its etymology, but the most widely accepted one is that it is shortened from Middle Korean ᄉᆞᇦ〯 (Yale: -sǒW-, object-honorific suffix) + ᄋᆞ쇼〮셔〮 (Yale: -òsyósyé, highly deferential imperative suffix):

ᄉᆞᄫᆞ〮쇼셔〮 (Yale: -sòW-ósyòsyé) > ᄉᆞ오〮쇼셔〮 (Yale: -sòw-ósyòsyé) > ᄉᆞ오〮 (Yale: -sòwó) > 소 (Yale: -swo)

For the declarative and interrogative suffixes, there are again many theories:

• Directly from the imperative suffix.
• Equivalent to ᄉᆞ오 (Yale: -sow(o)-, late form of ᄉᆞᇦ〯 (-sǒW-)) + 으이 (Yale: -ui, colloquial sentence-final suffix):

  ᄉᆞ외 (Yale: -sow-oy) > unattested *쇠 (Yale: *-swoy) > 소 (Yale: -swo)

• From the Early Modern polite suffix ᄉᆞᆸ (Yale: -sop) via intermediary 솝 (Yale: -swop); this is also ultimately from ᄉᆞᇦ〯 (Yale: -sǒW-).

The form is 오 (-o) after sonorants because Middle Korean ᄉᆞᇦ〯 (Yale: -sǒW-) was ᅀᆞᇦ〯 (Yale: -zǒW-) in such environments, and Middle Korean /z/ was subsequently deleted.

Usage notes

(modern usage)

• The semi-formal style is nowadays not commonly used in South Korea outside written commands, such as test questions or warnings, and literature. It is still popular in North Korea, although young women even there prefer the polite style.
• In South Korea, it tends to have a dialectal connotation because the decline of the suffix and its related speech levels is less severe outside the Seoul area.
• Standard Korean speakers are often confused or even offended by dialectal forms such as Hamgyong 소 (-so) or the related Gyeongsang 이소 (-iso, formal polite imperative suffix), because they tend to associate the suffix with a degree of self-assertiveness and hence lack of politeness.

(allomorphy with 오 (-o))

• After vowels, the liquid consonant ㄹ (l), and the copula stems, Standard Korean uses the allomorph 오 (-o); in the southern dialects of Gyeongsang and Jeolla, this becomes 요 (-yo) with a semivowel to break hiatus between vowels.
• However, there are certain differences between these two largely allomorphic forms, especially regarding the imperative mood. In Standard Korean, only 오 (-o) can be used for the imperative; after a consonant, the form 으오 (-euo) is used instead of 소 (-so). Conversely, in Gyeongsang Korean, only 소 (-so) can be used for the imperative, even if the stem ends in a vowel.

(allomorphy with 으오 (-euo))

• In Standard Korean, 소 (-so) can always be replaced by 으오 (-euo), although it is less common. As mentioned above, however, 으오 (-euo) is obligatory for the imperative.

Alternative forms

• 오 (-o), 우 (-u) — In Standard Korean, after vowels, ㄹ (l), and the copulas 이다 (-ida, “to be”) and 아니다 (anida, “to not be”)
• 요 (-yo) — In Jeolla and Gyeongsang, after vowels, ㄹ (l), and the copulas 이다 (-ida, “to be”) and 아이다 (aida, “to not be”)
• 으오 (-euo), 으우 (-euu) — alternative Standard Korean forms after consonants
• 으요 (-euyo) — alternative Jeolla form after consonants
