Make the intended event explicit
Write a short description of the meaning you want: someone waits for a friend at the station, a book is on a desk, or a person goes to a library. Give Mocchi that intention alongside the draft. This is especially useful when an error makes several interpretations possible. The task is to express your event accurately, not to find any fluent sentence containing the same nouns.
Keep the first editing example short. If several clauses and unfamiliar verbs are involved, simplify the event and check its core relationship. You can add the surrounding detail again after the central sentence is clear.
Read the place and object around the verb
駅で友達を待ちます describes waiting for a friend at the station. The station is where the activity happens, and the friend is the person being waited for in this construction. Ask Mocchi to explain those roles and compare them with a sentence about going to the station. The place word remains familiar while its relationship to the event changes.

| Japanese | Romaji | Meaning |
|---|---|---|
| 駅で友達を待ちます。 | Eki de tomodachi o machimasu. | I wait for a friend at the station. |
| 駅に行きます。 | Eki ni ikimasu. | I go to the station. |
Ask for a reason that survives another example
A useful correction explains what the particle represents in the sentence. Ask Mocchi to name that relationship in plain language, then apply it to a changed activity. If the explanation only says that one phrase sounds natural, request a clearer contrast. You need a reason you can test, not a claim that the same noun always takes the same particle.
Separate particle work from optional rewriting
A tutor may also improve vocabulary, politeness, or sentence flow. Ask it to keep those suggestions separate from the particle correction so you can identify the target decision. Too many simultaneous changes make it difficult to tell what fixed the original problem and may remove the chance to revise your own sentence.
Review the role you repeatedly confuse
If several edits involve action locations, make that the next short practice target. If the problem occurs only with an unfamiliar verb, learn its construction in a complete phrase. Tell Mocchi what the repeated issue looks like and ask for a fresh sentence before reviewing the old correction. This gives personalized feedback a concrete learning consequence instead of leaving the same error scattered across many polished drafts.
