Two jobs for one small suffix
Ppoi sits at the end of a word and softens it into an impression. With nouns and adjectives it means that something has the quality of the word: a colour that is close to white, an adult who acts a little like a child.
With a small group of verb stems it means something different: a tendency to do the action. Someone who is wasureppoi forgets things often, and someone who is okorippoi gets angry easily. Learners who know only one of these meanings are regularly surprised by the other.
| Japanese | Romaji | Meaning |
|---|---|---|
| 子どもっぽい | kodomoppoi | Childish: an adult acting like a child |
| 大人っぽい | otonappoi | Grown-up looking: often a compliment to a teenager |
| 忘れっぽい | wasureppoi | Forgetful: tends to forget |
| 怒りっぽい | okorippoi | Quick-tempered: tends to get angry |
How ppoi attaches
The attachment rules are simple, and the result always behaves like an i-adjective. That means you make the negative with ppokunai, the past with ppokatta, and the adverb with ppoku.
| Japanese | Romaji | Meaning |
|---|---|---|
| 白っぽい | shiroppoi | Whitish |
| 安っぽい | yasuppoi | Cheap-looking |
| 嘘っぽい | usoppoi | Sounds fake |
| 子どもっぽくない | kodomoppokunai | Not childish |
| 昔は子どもっぽかった。 | Mukashi wa kodomoppokatta. | I used to be childish. |
| Word type | How it attaches | Meaning it tends to give |
|---|---|---|
| Noun | Noun plus ppoi | Has the look or feel of the noun |
| i-adjective | Drop the final i, add ppoi | Somewhat, -ish, often cheap or rough |
| Verb | Masu stem plus ppoi, set words only | Tends to do it |
| Plain sentence | Plain form plus ppoi | Seems like: a very casual guess |
Tendencies: wasureppoi and its family
The tendency meaning is not productive. You cannot take any verb and add ppoi to say someone does it a lot; tabeppoi is not a word for a big eater. Learn the common set as vocabulary instead.
These words are handy for describing personality, including your own, and they sound natural in polite sentences with desu.
| Japanese | Romaji | Meaning |
|---|---|---|
| 最近、忘れっぽくて困ります。 | Saikin, wasureppokute komarimasu. | I have been forgetful lately, and it is a problem. |
| 父は怒りっぽいです。 | Chichi wa okorippoi desu. | My father is quick-tempered. |
| 飽きっぽい性格なんです。 | Akippoi seikaku nan desu. | I get bored of things easily. |
| 惚れっぽいタイプなんです。 | Horeppoi taipu nan desu. | I am the type who falls for people easily. |
Sentence ppoi in casual speech
Among younger speakers, ppoi also follows a whole plain-form clause and works like a relaxed mitai: it seems, it looks like. You will hear it constantly in chat and among friends.
It is informal enough that it does not belong in a meeting or in front of a client, but understanding it matters, because it turns up in almost every casual group conversation.
| Japanese | Romaji | Meaning |
|---|---|---|
| 明日は雨っぽいね。 | Ashita wa ame ppoi ne. | Looks like rain tomorrow. (casual) |
| 彼、今日は来ないっぽい。 | Kare, kyō wa konai ppoi. | Seems like he is not coming today. (very casual) |
| この店、もう閉まってるっぽいよ。 | Kono mise, mō shimatteru ppoi yo. | This shop looks like it is already closed. |
| 部長は会議に来られないようです。 | Buchō wa kaigi ni korarenai yō desu. | It seems the manager cannot make the meeting. (work-appropriate) |
Ppoi, rashii and mitai side by side
The three are easy to mix up because all of them can translate as like. The difference is attitude. Ppoi suggests something has some of the qualities without really being the thing, often with a hint of criticism. Rashii in its typicality sense means a good example of what the thing should be. Mitai is a plain comparison.
| Japanese | Romaji | Meaning |
|---|---|---|
| 大人なのに子どもっぽい。 | Otona na noni kodomoppoi. | An adult, but childish. |
| 子どもらしい笑顔ですね。 | Kodomo rashii egao desu ne. | Such a childlike smile. (approving) |
| 子どもみたいに喜んでいた。 | Kodomo mitai ni yorokonde ita. | He was as happy as a child. |
| 秋らしい天気ですね。 | Aki rashii tenki desu ne. | Real autumn weather, isn't it? (standard) |
| Pattern | What it says | Typical tone |
|---|---|---|
| ppoi | Has some qualities of the word, but is not really it | Casual, often mildly critical |
| rashii (typical) | A proper example of what the word should be | Usually approving |
| mitai | Resembles the word, a direct comparison | Neutral and casual |
For weather and seasons, rashii is the safer everyday choice, and akippoi tenki sounds more casual. The seemingness patterns are covered in more depth in the guide to sō, yō, mitai and rashii.
Using ppoi without misfiring
Most mistakes with ppoi are about tone rather than grammar. A few habits keep it working for you.
- Learn the tendency words as vocabulary; do not build new ones from other verbs.
- Remember that many ppoi words criticise: yasuppoi and kodomoppoi are not compliments.
- Use otonappoi to compliment a teenager and kodomoppoi only when you mean to tease.
- Keep sentence-level ppoi for friends and switch to yō desu at work.
- Conjugate it like an i-adjective: ppokunai, ppokatta, ppoku naru.
