Focus on what an action concerns
所 before a verb commonly builds an expression referring to what the action concerns, especially its object. It contrasts usefully with many 者 expressions, which refer to the participant doing or characterized by the action.
所
A reading procedure
- Find the verb after 所.
- Recover the missing participant from context.
- Treat the resulting phrase as a noun-like unit in the larger sentence.
所 is also a noun meaning a place. 所以 may describe a means or reason; modern “therefore” is not a safe default.

15 examples in context
七十而從心所欲，不踰矩
At seventy I followed what my heart desired without crossing the bounds.
心 supplies the desiring subject and 所欲 denotes what is desired. The age expressions organize the sequence. This is a contextual object-oriented use of 所, not the noun meaning a physical place.
Check your reading · What does 所欲 refer to?
What is desired.
觀其所由，察其所安
Observe what a person follows; examine where that person is at ease.
Each 所 phrase turns a relation into something to inspect. 其 supplies a contextual participant. The second phrase shows why a single English “thing which” cannot capture every 所 construction: a place or condition may be involved.
Check your reading · Why do the two 所 phrases need different English renderings?
Their governing predicates describe different relations.
所損益，可知也
What was reduced or added can be known.
所 takes the coordinated actions 損 and 益 into a noun-like expression. The historical discussion supplies whose changes are intended. 可知 is a modal predicate; the English passive “can be known” does not imply an overt passive marker in the source.
Check your reading · Does the English passive prove that a passive marker is written here?
No. The source has 可知 without an overt passive marker.
天地所以能長且久者
The reason heaven and earth can endure.
所以 packages a basis or reason, and the following text supplies it with 以其不自生. A modern automatic “therefore” for 所以 would invert the relation and obscure the explanatory frame.
Check your reading · Why is modern “therefore” a poor default here?
The phrase asks for the reason or basis of endurance.
吾所以有大患者，為吾有身也
The reason I have great troubles is that I have a body.
The 所以 expression establishes the reason to be explained; 為吾有身也 gives the explanation. The interpretation of 身 as body, embodied self, or personal existence affects the philosophy and should remain open to comparison.

為吾有身也.
故令之有所屬
Therefore give these something to which they belong.
所屬 denotes what the preceding items should be attached or directed to. The following paired instructions spell out that orientation. The referent of 之 depends on the prior three formulas; it is not recoverable from the isolated graph alone.
Check your reading · What does 所屬 denote?
The object or basis of belonging or attachment.
人之所畏，不可不畏
What people fear cannot simply be disregarded as an object of fear.
人之所畏 names the object of others’ fear. The two 不 operate at different levels in 不可不畏. Translating only one negative would reverse or weaken the constraint.
Check your reading · Why must both occurrences of 不 be considered?
They negate different parts of the modal expression.
此雖免乎行，猶有所待者也
Although this avoids going on foot, there is still something on which it depends.
雖 concedes an achievement, but 猶 preserves a remaining limitation. 所待 identifies what is depended on. 乎 follows 免 relationally here, unlike the sentence-final question particle in 不亦說乎.
Check your reading · Is 乎 a final question particle in 免乎行?
No. It introduces the relation to 行.
夫樂者、樂也，人情之所必不免也
Music is joy: it is something human feelings cannot altogether escape.
The repeated written 樂 connects music with enjoyment in an explanatory assertion. 者 marks the topic and 也 closes the identification; 所 introduces what people do not avoid. Modern reading labels can help distinguish the senses, but do not recover the exact ancient sounds of this wordplay.
Check your reading · Why should the two written instances of 樂 not receive an identical mechanical gloss?
One names music and the other its relation to enjoyment in the argument.
凡說之難：在知所說之心，可以吾說當之
The difficulty of persuasion lies in knowing the mind of the person being persuaded, so that one's proposal can fit it.
所說 points to the person addressed, while 吾說 names the speaker's proposal. The repeated graph 說 therefore has related but different roles. The final 之 refers to the target mind or its concerns; audience analysis is the issue, not merely fluency in speaking.
Check your reading · What is the contrast between 所說 and 吾說?
The person being persuaded versus what the persuader says or proposes.
詩者、志之所之也。在心為志，發言為詩。
Poetry is where intention goes: held in the heart it is intention; expressed in speech it is poetry.
This belongs to the received Great Preface, not to the verse of Guan ju. In 所之, 之 is read verbally as going or proceeding, unlike the linking 之 before 所. The formula offers an interpretation of poetry within a later framing text; it is not the anonymous song's own explanation of its composition.
Check your reading · Which textual layer contains this statement?
The received preface, not the poem's verse.
所謂伊人，在水一方
The one I speak of is on one side of the water.
所謂 presents the person referred to in the song, while 在 introduces location. English I is an interpretive supply, not an explicit pronoun in this line. 伊 should not be turned into a fixed modern gender label without evidence from the song.
Check your reading · Which information in the English rendering is not explicitly written as a pronoun?
The speaker I; the verse leaves the subject of speaking implicit.
己所不欲，勿施於人
Do not impose on others what you yourself do not want.
所不欲 forms the object-like topic picked up by the instruction. 勿 makes the clause a prohibition and 於人 identifies the recipient. The formula needs its interpersonal setting; it is not a claim that everyone shares precisely the same desires.
Check your reading · What distinguishes 勿 here from a description of what does not happen?
It directs the addressee not to act.
非所以內交於孺子之父母也，非所以要譽於鄉黨朋友也
It is not a means of forming ties with the child's parents, nor a way of seeking praise from neighbors and friends.
Repeated 非所以 excludes proposed motives for the alarm at a child approaching a well. 所以 refers to a means or reason here, not modern therefore. The passage asks readers to discriminate an immediate response from later calculations of advantage.
Check your reading · Which interpretation of 所以 would distort the argument?
Reading it mechanically as the modern conjunction therefore.
言者所以在意，得意而忘言
Words are a means for reaching meaning; once meaning is grasped, the words are forgotten.
所以 describes a means, not modern therefore. The preceding fish-trap and rabbit-snare comparisons support the relation between instrument and aim. The final question about speaking with someone who has forgotten words complicates any slogan that language is simply worthless.
Check your reading · What does the fish-trap comparison help identify?
Words as an instrument related to an aim, rather than as the aim itself.
