Find a base sentence you can own
Choose an ordinary event you can describe without copying a model. The base sentence should already communicate a complete action or state. If you cannot form it comfortably, ask Mocchi for help with that part before adding several new details. More complexity will not solve uncertainty about the main verb.
For this example, the basic message is that you watched a film. Say it aloud and explain what happened. Then decide what your listener would want to know next. That question gives the expansion a purpose instead of treating length as a score.
| Japanese | Romaji | Meaning |
|---|---|---|
| 映画を見ました。 | Eiga o mimashita. | I watched a film. |
| 友達と映画を見ました。 | Tomodachi to eiga o mimashita. | I watched a film with a friend. |
Add the detail that answers a real question
A listener might ask when you watched the film or who was with you. Add one answer to that question. Tell Mocchi which detail you are adding and ask it to inspect the new relationship. Keep the rest of the sentence stable so you can see what the addition does.
For example, adding a friend as company is different from making the friend the person who watched the film. Ask about that distinction if the particle changes. You are learning to control the message, rather than arranging extra words around a sentence that happens to sound familiar.
| Japanese | Romaji | Meaning |
|---|---|---|
| 土曜日に友達と映画を見ました。 | Doyōbi ni tomodachi to eiga o mimashita. | I watched a film with a friend on Saturday. |
| 家で映画を見ました。 | Ie de eiga o mimashita. | I watched a film at home. |
Keep one new structure in focus
Once time and place are comfortable, choose a relationship such as a reason or a contrast. Ask Mocchi for a brief explanation at your level and a nearby example. Add only that relationship to your own sentence. If both the grammar and the vocabulary are unfamiliar, simplify one of them.
Avoid requesting several advanced forms at once. A single meaningful connection gives you something specific to check and reuse. Explain what the listener should understand from the connection: the reason an activity happened, a contrast with an expectation or the order of two events.
Check a reason without changing the event
Suppose rain explains why you stayed home. Keep the activity and the place visible while you add the reason. Ask Mocchi whether the new sentence preserves that relationship and whether a shorter pair of sentences would be clearer for your current level.
Then change the situation. Use a different reason for a different ordinary decision. Close the original example before answering so you must choose the structure yourself. If you only remember the film sentence, return to the meaning of the connection and try another simple action.
| Japanese | Romaji | Meaning |
|---|---|---|
| 雨が降っていたので、家で映画を見ました。 | Ame ga futte ita node, ie de eiga o mimashita. | Because it was raining, I watched a film at home. |
| 時間がなかったので、タクシーで行きました。 | Jikan ga nakatta node, takushī de ikimashita. | Because I did not have time, I went by taxi. |
Compare your version with a rewrite carefully
If you use /correct for written feedback, read the explanation of each change. Ask whether it repairs an error, improves the flow or introduces a new meaning. A rewrite may be natural while using a structure you have not learned, so request a simpler alternative that preserves your intention.
Try reconstructing the revised sentence without looking. If you cannot explain one part, ask about that part before saving it as a model. The most useful sentence is one whose choices you can repeat in a new context, even if a more advanced version is available. Writing access depends on the features in your account.
Use expansion to support a clear short story
Build a small account of an event with a beginning, an important detail and a result. Some ideas may belong in separate sentences. Read the story aloud and notice where the listener needs a pause or another piece of information. Ask Mocchi which detail is necessary and which one distracts from the point.
End with a fresh story using the same kind of connection. You can prepare it in Mocchi, then use /kaiwa to find an AI Sensei conversation where the story fits. Your next practice target might be clearer order or a more useful reason, rather than simply adding more words.
