Japanese
koi
恋
koi (also ren in Sino-Japanese compounds) · koi [ko.i]
longing-love
What the gloss loses: “Love” suggests a state that could be complete. Koi, in its classical use, is almost grammatically incomplete: it leans. “Crush” is too light. “Passion” is too European. The word notices the interval, not the couple.
Etymology
A native Japanese word (yamato kotoba), written with the character 恋 (older 戀), whose Chinese value is liàn. The graph is a heart plus a phonetic; it was applied to Japanese koi, not born as Japanese. The spoken word is older than this spelling.
Do not etymologize koi from English “coy” or from the carp koi (鯉), a different word, different character, unfortunate homophone.
Morphology · Noun koi; adjective koishii (“yearned-for, missed”); verb compounds such as koi-suru, koi-wataru (“to go on longing”). Contrasts, in later usage, with 愛 ai.
Historical use
In waka and in Heian diaries, koi is the love of the night visit, the dawn leaving, the message, the not-yet. It is structured by absence even when the affair is current: the courtly calendar of waiting is part of the feeling. Izumi Shikibu writes from inside this grammar. Ono no Komachi’s poems make koi a weather that ages the body.
愛 ai is a Sino-Japanese word with a Buddhist history in which attachment (ai) is close to the problem of craving. In the Meiji period, translators of European literature and Christian texts rehabilitated ai as a counterpart to English love / Latin caritas, a more settled, more general, sometimes more altruistic love. Modern Japanese then inherited a split: koi as the ache toward someone; ai as the broader, often more committed word. The split is historical, not eternal. It is partly a translation-effect.
Popular psychology that says “koi is selfish, ai is true love” is doing moral work the older poems did not ask the word to do. Heian koi is not a failed ai. It is a different attention: to longing, to the night, to the fact that the beloved is not here.
Semantic range
- Yearning love; the ache of being toward someone.
- Romantic attachment in the process of happening.
- In compounds (恋愛 ren’ai): the modern category “romantic love.”
- Not the ordinary word for parental love or for liking (suki).
Semantic change
Meiji and later discourse folded Japanese feeling into a Western-shaped map: love as ai, romance as koi/ren’ai, like as suki. The Heian poems were then reread through that map. They can still be read the other way, as a literature of koi before ai was asked to be “love.”
Source · The Diary of Izumi Shikibu, where koi is not confessed as a theme but practiced as nights, poems, silences, and the question of whether he will come.

Portuguese saudade, Sanskrit viraha, and English longing all study absence. Koi is specific in making absence the ordinary climate of a love that may, in fact, be mutual, the man is only down the gallery, and still.
An open question
What does a literature trained on koi know that a literature trained on marriage-plots does not?
