Name the exact pair and why it feels confusing
Tell Mocchi which words you mix up and the context in which the confusion appears. A visual mix-up between compounds may need a different exercise from a semantic overlap between near-synonyms. Showing your first answer or explaining your reasoning helps the tutor choose a useful contrast instead of giving a long general definition of each word.
Limit the comparison at first. You do not need every related expression in the language to understand one pair. A clear distinction between two useful items is a stronger foundation than an impressive chart whose examples all remain difficult to remember.
Compare a reservation with a promise or arrangement
予約 is useful for a reservation or booking, while 約束 concerns a promise or arrangement between people. Compare a restaurant reservation with a promise to a friend. Ask Mocchi to explain which action each situation describes and then vary the setting. These examples establish a practical starting contrast without claiming that a single English word captures every use.

| Japanese | Romaji | Meaning |
|---|---|---|
| レストランを予約しました。 | Resutoran o yoyaku shimashita. | I made a restaurant reservation. |
| 友達と約束しました。 | Tomodachi to yakusoku shimashita. | I made a promise or arrangement with a friend. |
Ask for the clue before another definition
After seeing two examples, state what makes the choice different. Is the situation about booking a service, committing to another person, describing a state, or performing an action? A concise clue gives you something to retrieve in the next exercise. If the distinction remains vague, ask for a more concrete pair rather than repeating the same definitions in longer wording.
Create cards that test one intended decision
A card asking only for a broad translation such as arrangement may not tell you which word is intended. Add a short situation or ask which word fits a specific action. Keep the answer focused and include the reason on the back. Mocchi can suggest flashcards, but read the proposed prompts before saving them so the cards reflect the distinction you actually need.
Use a fresh example to decide whether the pair is clearer
Choose the word in a new situation without reopening the original examples. Explain your reason before checking the answer. If the same confusion returns, revise the clue or make the contrast smaller. If it is reliable, add occasional mixed review rather than keeping both words isolated forever. The aim is choosing the useful vocabulary in context, not simply recognizing two separate definitions.
