Mutual trust runs in both directions
- Two teammates each trust the other: we我们each other彼此trust信任。 fits that relationship. “I trust her, but she does not trust me” describes one-way trust and does not support the same mutual claim.
- Identify the participants before describing reciprocity. Knowing that both people joined a team does not prove that they trust each other; the membership list has not read their minds.
Two teammates both trust the other. What does 我们彼此信任。 communicate?

The trust runs in both directions within the group. 彼此 can also occur as an object, as in 了解彼此. 互相 usually modifies an action; the two often overlap in meaning.
Use each other彼此 before the action or as its object
- we我们each other彼此trust信任。 and we我们each other互相trust信任。 can both describe mutual trust. Before this verb, the two expressions overlap in meaning.
- we我们understand了解each other彼此。 uses each other彼此 as the object: we understand each other. Do not replace that object mechanically with each other互相; the usual action-modifying pattern is we我们each other互相understand了解。
we我们each other彼此trust信任。
Using the lesson pattern in this demonstrated example: We trust each other: 我们 ____ 信任。

彼此 + 動詞 ＝ お互いに：彼此信任.
Read the same relationship in a different arrangement
- we我们each other彼此understand了解。 and we我们understand了解each other彼此。 both express understanding of one another. A changed position can change the construction without changing this basic reciprocal meaning.
- we我们all / both都understand了解teacher老师。 has a different object: each of us understands the teacher. It does not itself state that we understand one another. Identify who is related to whom rather than selecting a familiar word alone.
we我们understand了解each other彼此。
How does 彼此 differ from 互相?

彼此 is a reciprocal pronoun; 互相 is normally an adverb. Both can occur before 信任.
Which sentence uses 彼此 as the object of 了解?

彼此 follows 了解 as its object. The second expresses reciprocity with an action modifier; the third names a teacher as the object.
Mutual does not mean identical in amount
- they他们each other彼此assistance帮助。 describes helping one another. It does not establish that each person spent the same number of minutes, gave equal money or performed the same task.
- In a larger group, context identifies the reciprocal relationship. Do not infer from each other彼此 alone that every possible pair performed every action equally often; that stronger description needs more detail.
In the two-teammate case, 彼此信任 describes trust in both directions.
難易度 1/5 · 100 コイン + 今日初回完了時に小ボーナス付与
In this case each teammate trusts the other; the reciprocal description does not measure equal amounts of trust or prove every possible group relationship.
彼此信任 describes only one person's trust.

彼此 can also occur as an object, as in 了解彼此. 互相 usually modifies an action; the two often overlap in meaning. The trust runs in both directions within the group.
他们彼此帮助 alone proves that each person spent exactly the same number of minutes helping.

Reciprocity does not specify equal quantities.
you and me both彼此彼此 can acknowledge a shared situation
- In a friendly exchange, one learner says “My handwriting is messy”; the other replies you and me both彼此彼此. In that context, the reply means roughly “same here”, acknowledging a similar situation.
- The repeated expression does not require an object after it in this reply. This conversational use differs from understand了解each other彼此. Interpret the exchange before translating every occurrence as a verb phrase with “each other”.
Transfer reciprocity to a new situation
- Two colleagues give each other reminders: they他们each other彼此to remind提醒。 can describe reciprocal reminders. If only one sends reminders, state that direction instead; a reciprocal word cannot supply missing participation.
- Meaning reference: Ministry of Education dictionary: each other彼此. The teammate and reminder cases are original. Compare the unit reference with the earlier each other互相 lesson.
- Check participants, direction and construction; mutual action does not establish equal quantities.
After a friend says “My handwriting is messy”, 彼此彼此 is used as a friendly reply. What does it acknowledge here?

In this exchange the repeated phrase acknowledges similarity, roughly same here.
Recall the situation: Mutual trust runs in both directions. Decide what the speaker wanted to communicate. Close the examples. Say a Mandarin response, then write it in Chinese. Explain briefly in English what the lesson’s pattern adds. Compare with the model, then change one detail and try again.
This is supported productive practice. Compare meaning and structure; your answer need not copy the model. A partner or teacher must hear the spoken response to comment on pronunciation.
