Three suffixes, three pictures
All three suffixes attach straight to a noun with no particle: doro darake, doro mamire, ii koto zukume. They then behave like a na-adjective or a noun. To end a sentence, add da or desu. To modify a noun, add no. To describe a result, add ni before naru or suru. This shared grammar makes them easy to build. The work is choosing the right one for the picture in your head.
Darake is the widest. It means scattered with or riddled with, and it takes both physical things, such as holes, dust and blood, and abstract ones, such as mistakes, debts and lies. Mamire is narrow: it only takes substances that coat a surface, so blood, sweat, mud, oil, dust, sand and flour, but never mistakes. Zukume is different in spirit: it means composed entirely of, and it describes what a day, an outfit, a meal or a life is made of.

Darake: scattered all over with something unwanted
Darake gives the image of many small things spread everywhere, so that you cannot look without seeing them. Because the speaker is usually complaining, the noun is almost always something unpleasant: kizu, scratches; ana, holes; hokori, dust; shakkin, debts; uso, lies. It is not a formal word, and it is at home in complaints, teasing and casual description. In a report you would replace it with ga ōi or ni michite iru.
The negativity is built in even when the noun is neutral. Hana darake, covered in flowers, sounds as if the flowers are a mess rather than a delight, so for a happy image you would say hana ga ippai or hana de ippai. This is the main trap for learners: darake is not just a lot of, it is a lot of, and I am not pleased. The one common exception is affectionate exaggeration, as when a parent laughs at a child who is chokorēto darake, covered in chocolate.

Mamire: coated in a substance
Mamire comes from the verb mamireru, to be smeared, and it keeps that physical sense. The noun must be a substance that can stick to a surface: chi, blood; ase, sweat; doro, mud; abura, oil or grease; hokori, dust; suna, sand; komugiko, flour. The picture is of a coating, thick and continuous, rather than a scattering. That is why doro mamire feels muddier than doro darake: with mamire the mud is caked on.
Because it is so physical, mamire cannot take abstract nouns. Machigai mamire and uso mamire are wrong. The only common figurative use is in a few set phrases, such as ase mamire ni natte hataraku, work until soaked in sweat, where the sweat is still real. Mamire is neutral to slightly vivid in tone, and it appears in stories, sports reports and everyday talk about children, cooking and cleaning.
| Japanese | Romaji | Meaning |

| 血まみれの手で電話をかけた。 | Chi mamire no te de denwa o kaketa. | He made the call with blood-covered hands. |
| 料理の後、台所が油まみれになった。 | Ryōri no ato, daidokoro ga abura mamire ni natta. | After cooking, the kitchen was covered in grease. |

| 倉庫の箱はほこりまみれだった。 | Sōko no hako wa hokori mamire datta. | The boxes in the warehouse were caked in dust. |
Zukume: made entirely of one thing
Zukume comes from tsukusu, to exhaust or use up, and it means that something is made up of one thing from start to finish. It is the only suffix of the three that is comfortable with pleasant nouns. Ii koto zukume, nothing but good things; gochisō zukume, a spread of delicacies; iwai zukume, one celebration after another. It also works with neutral descriptions, especially colours: kuro zukume no fuku, an all-black outfit, is common.
Zukume is a little literary and often appears in set phrases rather than free combinations. It is the word for describing a day, a week, a year, a meal, an outfit or a set of rules. With negative nouns it becomes a complaint about there being nothing else: kisoku zukume, nothing but rules; kaigi zukume no isshūkan, a week of back-to-back meetings. The difference from darake is the picture: darake scatters things across a surface, zukume fills a container to the brim with a single ingredient.
| Japanese | Romaji | Meaning |
|---|---|---|
| 今年は結婚、昇進と、お祝いずくめの一年でした。 | Kotoshi wa kekkon, shōshin to, iwai zukume no ichinen deshita. | This year was one celebration after another: a wedding, a promotion. |

| 今週は会議ずくめで、自分の仕事ができない。 | Konshū wa kaigi zukume de, jibun no shigoto ga dekinai. | This week is back-to-back meetings and I can't do my own work. |
Darake, mamire and zukume side by side
The table lists common combinations and shows which suffix each noun takes. A few nouns accept two suffixes with a shift in image, and those are the ones to study closely.
| Expression | Reading | Meaning and feel |
|---|---|---|
| 泥だらけ | doro darake | Muddy all over, spattered; negative |
| 泥まみれ | doro mamire | Caked in mud; vivid, physical |
| 間違いだらけ | machigai darake | Riddled with mistakes; negative, abstract |
| 傷だらけ | kizu darake | Covered in scratches or scars |
| 血まみれ | chi mamire | Covered in blood; only mamire |
| 汗まみれ | ase mamire | Drenched in sweat; only mamire |
| 油まみれ | abura mamire | Coated in grease |
| ほこりだらけ | hokori darake | Dusty, specks everywhere |
| いいことずくめ | ii koto zukume | Nothing but good things; positive |
| 黒ずくめ | kuro zukume | All in black; neutral |
| 規則ずくめ | kisoku zukume | Nothing but rules; negative |
| ごちそうずくめ | gochisō zukume | A feast of treats; positive |
Doro is the clearest test case. Doro darake describes spatters and patches; doro mamire describes a coating so thick you cannot see the cloth. Both are correct, and the choice tells the listener how bad it was.
Ippai and dake: the near neighbours
Ippai means full or a lot, and it is neutral. Heya ga hito de ippai, the room is full of people; hana ga ippai saite iru, lots of flowers are blooming. Ippai does not attach to the noun directly; it takes de or ga. Use ippai when you want quantity without judgement, or when the fullness is pleasant. It cannot express the riddled-with image of darake or the coated image of mamire.
Dake means only and limits rather than fills. Kisoku dake, only rules, states that nothing else exists; kisoku zukume, nothing but rules, says the whole experience is saturated with them. Learners sometimes hear zukume as a stronger dake, which is not far off, but zukume paints a scene while dake draws a line. There is also bakari, nothing but, which is close to zukume in meaning but attaches to actions and habits as much as things: niku bakari taberu, eat nothing but meat.
- Ippai: a lot, full; neutral or pleasant; takes de or ga, not attached
- Darake: scattered with something unwanted; attached; negative
- Mamire: coated in a substance; attached; physical
- Zukume: consisting entirely of; attached; positive, neutral or negative
- Dake: only; a limit, not a description of fullness
- Bakari: nothing but; used for repeated actions and habits
If you can put the noun in a container and count how full it is, ippai. If it is spattered across a surface, darake. If it is smeared on, mamire. If the whole thing is made of it, zukume.
Example scenes from everyday life
The suffixes come alive when tied to real moments. After a rainy football match, a parent sees doro darake no yunifōmu and doro mamire no sune, muddy kit and mud-caked shins. In the kitchen, a first attempt at tempura leaves the hob abura mamire and the recipe page shimi darake, stained all over. Back at the office, a draft returns from the boss akaji darake, covered in red ink, and the following week is kaigi zukume. On holiday at a ryokan, the dinner is gochisō zukume and the return train is tsukareta hito darake, full of tired people.
| Japanese | Romaji | Meaning |
|---|---|---|
| 雨の試合で、ユニフォームが泥だらけになった。 | Ame no shiai de, yunifōmu ga doro darake ni natta. | The kit got covered in mud in the rainy match. |
| 天ぷらを揚げたら、コンロが油まみれになった。 | Tenpura o agetara, konro ga abura mamire ni natta. | When I fried tempura, the hob got coated in oil. |
| 原稿が赤字だらけで返ってきた。 | Genkō ga akaji darake de kaette kita. | The draft came back covered in red corrections. |
| 来週は出張ずくめで、家に帰れない。 | Raishū wa shutchō zukume de, ie ni kaerenai. | Next week is nothing but business trips and I can't get home. |
| 帰りの電車は疲れた人だらけだった。 | Kaeri no densha wa tsukareta hito darake datta. | The train home was full of tired people. |
| 公園は花でいっぱいで、気持ちがよかった。 | Kōen wa hana de ippai de, kimochi ga yokatta. | The park was full of flowers and it felt wonderful. |
Common mistakes and how to avoid them
The first mistake is using darake for something pleasant. Tomodachi darake, omoide darake and hana darake all sound like complaints. Use ippai, takusan or, for a whole made of one thing, zukume. The second is attaching mamire to an abstract noun: machigai mamire and shigoto mamire are wrong, because nothing physical is being smeared. Keep mamire for substances.
Third, learners insert a particle: doro no darake and doro ni mamire are not the pattern; the suffix attaches directly. The verb mamireru does take ni, as in doro ni mamireru, but the suffix form is doro mamire. Fourth, zukume is not a free suffix for every noun; it is most natural in the set combinations shown above and with colours, koto, iwai, kisoku, gochisō and events such as kaigi and shutchō. If you are unsure, say bakari or dake instead. Finally, do not double up: doro darake de ippai is redundant. Choose one image and let it stand.
| Japanese | Romaji | Meaning |
|---|---|---|
| 友達がいっぱいできた。 | Tomodachi ga ippai dekita. | I made lots of friends. (not tomodachi darake) |
| 仕事だらけの毎日だ。 | Shigoto darake no mainichi da. | Every day is nothing but work. (darake, not mamire) |
| 靴が泥まみれになってしまった。 | Kutsu ga doro mamire ni natte shimatta. | My shoes ended up caked in mud. (no particle before mamire) |
| いいことずくめの年になりますように。 | Ii koto zukume no toshi ni narimasu yō ni. | May it be a year full of good things. |
| 最近、コンビニのご飯ばかりだ。 | Saikin, konbini no gohan bakari da. | Lately it's nothing but convenience store food. (bakari for habits) |
