Sentence-final 了 for a New Situation in Chinese
变化态：句末“了”
Sentence-final 了 presents a new situation or a change that now holds, such as becoming ill, rain getting lighter, or reaching mealtime. It scopes over the whole proposition and is not simply a past-tense marker. The completed-action suffix 了 after a verb is a related but distinct use.

Sentence-final 了 presents a new situation or a change that now holds, such as becoming ill, rain getting lighter, or reaching mealtime. It scopes over the whole proposition and is not simply a past-tense marker. The completed-action suffix 了 after a verb is a related but distinct use. Keep the model Subject + Predicate + 了 visible while you compare each sentence.
她病了。
She has become ill.
Choose the right context
Present a state that has just changed. Announce that a new situation now holds. Mark a contextually relevant transition at sentence end.
雨小了。
The rain has become lighter.
Respect the boundary
Do not move 了 before the predicate. Do not treat every past event as requiring sentence-final 了. Do not confuse this clause-level change with the verb suffix that marks completion.
她了病。
(She le ill.)
Repair the pattern
Sentence-final 了 is placed before the predicate: The clause-level particle follows the proposition whose changed situation it presents. The change marker interrupts the subject and adjective predicate: The new-state 了 belongs after the predicate 小, not between the subject and predicate.
她病了。
Use the repaired structure without changing the intended meaning.

08 / QUESTIONS
Sentence-final 了 for a New Situation Questions
Does sentence-final 了 always mean past tense?
No. It presents a new situation relative to context, which can concern the present or an imminent change.
Is this the same as verb-suffix 了?
They are related historically and may co-occur, but the verb suffix presents completion while sentence-final 了 presents a changed situation.
