still existing; not destroyed
Still here and not destroyed or lost, often used about old things like books, buildings, or animals.
用法模式：
[extant] [noun]
常见错误：
Learners sometimes confuse "extant" with the much more common word "extent" (meaning how large or how much). They may also try to use "extant" in everyday contexts where "existing" or "current" is more natural. "Extant" is typically used in formal or academic writing, often about old or rare things (texts, species, buildings).
近义词
existing (More general and common; does not carry the usual idea of being old or rare the way "extant" often does.)
|
surviving (Emphasizes that something has continued to exist despite time or danger; slightly more emotional than the neutral, formal "extant".)
|
remaining (Focuses on what is left after other things are gone; less formal and not limited to old or historical items.)
反义词
extinct (Used especially for species that no longer exist anywhere; often directly contrasted with extant species.)
|
lost (Suggests that something once existed but can no longer be found; broader and less formal than "extant".)

currently existing or in force (law)
Existing now and still legally or officially in use, especially about laws or rules.
用法模式：
[extant] [law/rule/regulation/policy]
常见错误：
Learners may not realize that in legal or official writing, "extant" often focuses on whether a rule or document is still in force now, not on age or rarity. In everyday speech, people usually say "current law" or "rules that are still in effect" instead of "extant law."
近义词
currently in force (A clear legal phrase that directly states that a law or rule is active now; slightly longer but less formal than "extant".)
|
valid (General term for something legally or officially acceptable now; broader and more common than the formal, specific "extant".)
反义词
repealed (Used for laws or regulations that have been officially removed; contrasts with laws that are still extant.)
|
expired (Describes contracts, licenses, or similar documents that are no longer in effect because their end date has passed.)
