Connecting Adjectives in Japanese: Kute, De and Nakute for Longer Descriptions

I-adjectives: drop i, add kute

Every i-adjective ends in i in its dictionary form: takai, yasui, atarashii, omoshiroi. To connect it to another description, remove that final i and add kute. Takai becomes takakute, omoshiroi becomes omoshirokute. The joined adjective has no tense of its own; the last word in the sentence decides whether the whole thing is present, past, polite or plain.

One irregular form matters: ii, good, uses the older stem yo, so the te form is yokute. Kakkoii, cool, therefore becomes kakkoyokute. Everything else follows the rule, including long forms such as urayamashii (urayamashikute) and the tai form of verbs, which is an i-adjective too: ikitakute.

Na-adjectives and nouns: add de

Na-adjectives such as shizuka, kirei, benri and genki do not conjugate on their own; they borrow the copula. The te form of da is de, so the connected form is simply the adjective plus de: shizuka de, kirei de. Nouns join in exactly the same way, because a noun predicate is also noun plus da: gakusei de, Nihonjin de, ame de.

This means you can mix word classes freely. Kirei de shizuka na machi, a clean, quiet town, joins two na-adjectives with de and then attaches to the noun with na. Kare wa isha de, totemo shinsetsu desu, he is a doctor and very kind, joins a noun to a na-adjective. When a na-adjective comes last before a noun, it takes na; when it ends the sentence, it takes desu or da.

The negative: nakute

To connect a negative description, start from the nai form and change nai to nakute. Takakunai becomes takakunakute; omoshirokunai becomes omoshirokunakute. For na-adjectives and nouns, the negative is ja nai or de wa nai, so the te form is ja nakute: shizuka ja nakute, gakusei ja nakute. Nai on its own, the negative of aru, becomes nakute too: jikan ga nakute.

Nakute has two jobs, just like kute. It can simply list a negative quality alongside another one: takakunakute oishii, not expensive and tasty. It can also give a reason: okane ga nakute kaemasen, I cannot buy it because I have no money. A third pattern, ja nakute, is used for correction: kōhī ja nakute, kōcha desu, not coffee, tea.

Kute as a reason: isogashikute ikemasen

The te form of an adjective very often carries the meaning because, and this is one of the most useful patterns in daily speech. Isogashikute ikemasen means I am too busy to go. Atsukute nemurenai means it is so hot that I cannot sleep. The cause comes first, the result second, and the kute quietly links them.

This reason use has a restriction: the result should be something you do not control. Inability (ikemasen, nemurenai), feelings (ureshii, komaru, bikkuri shita) and states (tsukareta, okureta) all work. A deliberate action, a request or a suggestion does not: for I am tired, so let's go home, use tsukareta kara kaerō, not tsukarete kaerō. When you want to make the cause explicit or to persuade, kara and node are safer.

Nouns and na-adjectives do the same with de: ame de shiai ga chūshi ni natta, the match was cancelled because of rain. The reason kute also opens polite requests. Samukute, mado o shimete mo ii desu ka states the problem, then asks lightly. To ask for something to be made a certain way, adjectives use ku shite or ni shite: chiisaku shite kudasai, shizuka ni shite kudasai.

Order, agreement and contrast

Kute and de imply that the descriptions sit comfortably together. Yasukute oishii, cheap and tasty, works because both are good news. Yasukute mazui, cheap and bad, also works, because both explain each other. What sounds odd is joining an unwelcome quality to a welcome one with kute, as if there were no tension between them. For that, Japanese uses ga or kedo: yasui desu ga, amari oishikunai desu, it is cheap, but not very tasty.

Order is flexible but not random. Speakers usually put physical or objective facts first and the judgement last, so hirokute akarukute, sugoku ii heya desu, spacious and bright, a really good room. The last adjective is the one that carries the tense and the emphasis, so put your main point there. If a description is long, a comma pause after two or three items keeps it easy to follow.

• Same direction, joined with kute or de: yasukute oishii, shizuka de kirei
• Opposite direction, joined with ga or kedo: yasui kedo mazui, kirei da ga takai
• Objective before subjective: ōkikute atarashikute, sugoku suteki
• Main point last: it takes the tense and the stress
• Long chains: pause after two or three, then continue

A quick test for contrast: if you could put but between the two English adjectives, do not use kute. If you could put and, kute is right.

The te forms side by side

The table shows the joining form and the negative joining form for a set of everyday words across all three classes.

Long descriptions of people and places

Real descriptions mix all of the above: an appearance, a personality, a job, a place. Start with the topic, list the objective facts with kute and de, and land on the judgement. Ane wa se ga takakute, kami ga nagakute, totemo akarui hito desu, my older sister is tall, has long hair and is a very cheerful person. Body features use the pattern se ga takai, me ga ōkii, kami ga nagai, each joined with kute.

For places, combine location, size and feel. Watashi no machi wa umi ni chikakute, shizuka de, natsu wa kankōkyaku ga ōi desu, my town is near the sea, quiet, and full of tourists in summer. Notice that a verb clause can join the chain too, using the verb's own te form or a comma break. Keep sentences to three or four descriptions; beyond that, start a new sentence with sore ni or soshite.

Common mistakes and how to fix them

The first mistake is using de with an i-adjective or kute with a na-adjective: ōkii de, kirei kute. Check the dictionary form: if it ends in i and is not one of the false friends kirei, kirai, yūmei, then kute. The second is ikute for good; the form is yokute. The third is putting tense in the middle of the chain, takakatta kute, which is never correct.

The fourth mistake is stringing contrasting qualities with kute, benri de takai, which sounds as if you have not noticed that one is a downside. Use ga or kedo. The fifth is using the reason kute before a deliberate action or a request: samukute mado o shimete kudasai is a little off, because the request is your decision. Samui node or samui kara fixes it. And finally, watch the negative: takai ja nakute is wrong for an i-adjective; it must be takakunakute.
