因而: Introducing a Formal Result in Chinese
……，因而……
因而 introduces a result that follows logically from the preceding cause or situation. It normally begins the result clause and has a relatively formal, written tone. Unlike 因为, it does not introduce the cause itself. The two clauses must form a genuine cause-result relation rather than a mere chronological sequence.

Read the structure
因而 introduces a result that follows logically from the preceding cause or situation. It normally begins the result clause and has a relatively formal, written tone. Unlike 因为, it does not introduce the cause itself. The two clauses must form a genuine cause-result relation rather than a mere chronological sequence. Keep the model Cause Clause, + 因而 + Result Clause visible while you compare each sentence.
他生病了，因而没来上课。
He was ill and therefore did not come to class.
Choose the right context
Connect illness to absence: 他生病了，因而没来上课。 Connect achievement to a reward: 她完成任务，因而受到奖励。 Present a formal analytical consequence: 成本上升，因而价格调整。
她按时完成了任务，因而受到公司的奖励。
She completed the task on time and therefore received a company reward.
Respect the boundary
Do not place 因而 before the cause clause as a substitute for 因为. Do not pair clauses that are merely sequential with no causal relation. Do not add 所以 directly beside 因而; choose one result connector.
他生病了，没来因而上课。
(He was ill and did not come therefore attend class.)
Repair the pattern
因而 is inserted inside the result predicate: 因而 introduces the whole result clause and must precede 没来上课. Two result connectors are redundantly stacked: 因而 and 所以 both introduce the result here; stacking them is redundant and ungrammatical.
他生病了，因而没来上课。
Use the repaired structure without changing the intended meaning.

- Connect illness to absence: 他生病了，因而没来上课。
- Connect achievement to a reward: 她完成任务，因而受到奖励。
- Present a formal analytical consequence: 成本上升，因而价格调整。
Do not use it when
- Do not place 因而 before the cause clause as a substitute for 因为.
- Do not pair clauses that are merely sequential with no causal relation.
- Do not add 所以 directly beside 因而; choose one result connector.
05 / REPAIR
Compare Right and Wrong
Compare the smallest meaningful change. Each explanation identifies a placement, scope, form, or clause relationship instead of treating the whole sentence as one undifferentiated mistake.
他生病了，没来因而上课。
他生病了，因而没来上课。
因而 is inserted inside the result predicate
因而 introduces the whole result clause and must precede 没来上课.
他生病了，因而所以没来上课。
他生病了，因而没来上课。
Two result connectors are redundantly stacked
因而 and 所以 both introduce the result here; stacking them is redundant and ungrammatical.
他生病了，没来因而上课。
