Meaning & Usage
The grammar pattern がちだ (gachi da) expresses a tendency or inclination for something to happen frequently, or for someone to be prone to a particular state or action. Essentially, it signifies that a certain situation or behavior occurs often.
While it can simply mean 'tend to,' it almost always carries a subtle, often negative, or undesirable nuance. This is a crucial aspect to remember: がちだ typically describes habits, situations, or states that are not ideal, are problematic, or are slightly regrettable.
Think of がちだ as describing a recurring pattern or a susceptibility. For instance, if someone 'tends to forget things,' it implies that forgetting is common for them, and it's generally not a positive trait. Similarly, if a machine 'tends to break down,' it suggests frequent, undesirable malfunctions.
This pattern paints a picture of something happening more often than one might wish, or more often than is considered normal or healthy. It can be translated into English using phrases like 'tend to,' 'prone to,' 'apt to,' 'often,' or 'frequently.' Always keep its underlying negative connotation in mind.
Unlike simple statements of frequency like 'often' or 'sometimes,' がちだ highlights a characteristic or an inherent susceptibility. It suggests that the subject has a tendency for something to happen, implying a somewhat ingrained pattern rather than just a frequent occurrence.
For example, consider the difference between 「彼は遅刻することが多い。」 (He is often late.) and 「彼は遅刻がちだ。」 (He tends to be late.). The latter emphasizes his predisposition or habit of being late, framing it as a characteristic that's perhaps a bit problematic. This makes the statement more critical or reflective than a purely factual report of frequency.
You can use がちだ in both spoken and written Japanese. It lends a slightly more formal or established tone than some casual expressions of frequency. It's suitable for discussing general observations, personal habits (often self-deprecatingly), or common societal trends. It's less likely for one-off events and more for consistent, recurring patterns. When you encounter がちだ, ask yourself: "Is this a desirable or undesirable tendency?" The answer will almost invariably point towards the latter.
Structure & Formation
Forming がちだ is straightforward. It primarily attaches to two types of words: verbs and nouns.
1. Verb (ます-form) + がちだ
To use がちだ with a verb, convert the verb into its ます-form (remove ます) and then append がちだ.
| Verb Type | Plain Form | ます-form (stem) | がちだ Form | Meaning |
|---|---|---|---|---|
| Group 1 Verb | 休む (yasumu) | 休み (yasumi) | 休みがちだ | Tend to rest / take days off |
| Group 2 Verb | 忘れる (wasureru) | 忘れ (wasure) | 忘れがちだ | Tend to forget |
| Irregular Verb | する (suru) | し (shi) | しがちだ | Tend to do |
Note: Use the ます-stem without the ます ending.
2. Noun + がちだ
When attaching がちだ to a noun, simply place がちだ directly after the noun.
| Noun Type | Noun | がちだ Form | Meaning |
|---|---|---|---|
| Common Noun | 病気 (byōki) | 病気がちだ | Prone to illness |
| Common Noun | 遅刻 (chikoku) | 遅刻がちだ | Prone to lateness |
| Abstract Noun | 留守 (rusu) | 留守がちだ | Prone to being away / not home |
In both cases, がちだ functions similarly to an な-adjective, so it can be conjugated like one (e.g., がちです, がちなN, がちだった, etc.).

Common Mistakes
Mistake 1: Using がちだ for positive or neutral tendencies.
がちだ inherently carries a negative or undesirable nuance. It's not typically used for positive habits or neutral facts about frequency.
❌ 私は毎日運動しがちだ。
✅ 私は毎日運動する習慣がある。(I have a habit of exercising every day.)
✅ 私は毎日運動することが多い。(I often exercise every day.)
Explanation: Exercising daily is generally a good habit. Using がちだ here would imply it's a problematic or regrettable tendency, which is incorrect. For positive or neutral habits, use expressions like 「～習慣がある」 or 「～ことが多い」.
Mistake 2: Confusing がちだ with ～やすい (yasui).
While both can imply "prone to," ～やすい emphasizes ease or susceptibility, which can be positive or negative. がちだ strongly implies a negative, undesirable pattern.
❌ このカメラは使いがちだ。(Incorrectly implying: This camera tends to be used easily.)
✅ このカメラは使いやすい。(This camera is easy to use.)
✅ このカメラは故障しがちだ。(This camera tends to break down.)
Explanation: 「使いやすい」 focuses on the ease of use. If you want to say the camera often breaks, which is a negative tendency, then 「故障しがちだ」 is appropriate. They are not interchangeable for all contexts.
Mistake 3: Incorrect verb form (using plain form instead of ます-form).
がちだ attaches to the ます-stem of verbs.
❌ 彼は忘れるがちだ。
✅ 彼は忘れがちだ。
Explanation: The plain form 「忘れる」 is incorrect. It should be the ます-stem 「忘れ」.
Mistake 4: Using がちだ directly with adjectives.
がちだ primarily connects to verbs (ます-form) and nouns. It generally does not attach directly to adjectives (い-adjectives or な-adjectives).
❌ 彼女は寂しがちだ。
✅ 彼女は寂しくなりがちだ。(She tends to get lonely.)
✅ 彼女は寂しがっている。(She is feeling lonely.)
Explanation: To express a tendency related to an adjective, you would typically use a verb form like 「～くなる」 (to become) or 「～になる」, and then attach がちだ to that verb's ます-stem. For example, 「寂しい」 (lonely) becomes 「寂しくなる」 (to become lonely), and then 「寂しくなりがちだ」.
Cultural Notes
In Japanese culture, acknowledging one's own shortcomings or negative tendencies is often seen as a sign of humility and self-awareness. がちだ is frequently used in this context. For example, a person might say 「私は締め切りを忘れがちなので、メモを取っています。」 (I tend to forget deadlines, so I take notes.) This self-deprecating usage softens the admission of a flaw and shows an attempt at mitigation.
When describing others, がちだ can be a gentler way to point out a recurring (and often undesirable) behavior compared to more direct or accusatory language. For instance, saying 「彼は遅刻がちだ。」 (He tends to be late.) presents it as an observation of his general pattern. This sounds less confrontational than 「彼はよく遅刻する。」 (He is often late.), aligning with the Japanese preference for indirect communication, especially on sensitive topics.
You will also encounter がちだ in news reports, business contexts, and general observations about society or groups of people. For example, a news report might state 「最近の若者は、家で過ごしがちだ。」 (Recent young people tend to spend time at home.). This describes a social trend that might be viewed with slight concern or as a deviation from previous norms. Its usage often reflects a subtle judgment about the normalcy or desirability of the described tendency.

JLPT Tips
When preparing for the JLPT N3 exam, understanding the subtle nuances of がちだ is key. The most important distinction to remember is its inherent negative connotation. If a sentence describes a positive habit or a neutral frequency, がちだ is likely not the correct choice. For example, if a question presents an option using がちだ for something like "He tends to help people," it's almost certainly incorrect because helping people is a positive trait.
Pay close attention to the word type that がちだ attaches to. Remember it's always the ます-stem for verbs and directly after nouns. Mixing these up is a common trap in multiple-choice questions.
Another common test strategy involves distinguishing がちだ from similar grammar points like ～やすい and ～傾向がある. Look at the overall context of the sentence. Does it imply an undesirable outcome or a problematic pattern? If so, がちだ is a strong candidate. If the sentence is merely stating ease or a neutral tendency, then ～やすい or ～傾向がある might be more appropriate.
Finally, practice forming and understanding sentences with がちだ in various contexts, especially those involving common undesirable habits (e.g., forgetting things, getting sick easily, being late, making mistakes). The more you expose yourself to correct usage, the more naturally you'll identify it in the exam. Always ask yourself: "Is this tendency something that someone would ideally want to avoid or improve?" If the answer is yes, then がちだ is very likely the right choice.
