extinct + noun (species, language, civilization)

用法筆記

Typically used with the verbs become, go, or be declared. Common nouns this adjective modifies include species, language, civilization, culture, tradition, and custom. A species is not called extinct until every last individual has been confirmed dead or gone.

常見錯誤

Pandas are extinct.
Pandas are endangered.
💡extinct means completely gone; endangered means at serious risk but still surviving.
That old custom is now extincted.
That old custom is now extinct.
💡extinct is an adjective, not a verb. Do not add -ed.

2. describes a volcano that has not erupted in recorded history and is not expected

2.形容詞B2
釋義

死火山

火山不再活躍

describes a volcano that has not erupted in recorded history and is not expected to erupt again, so its cone and crater remain but there is no molten rock activity below the surface.

例句

Mount Hoei in Japan is an extinct volcano that has not erupted for over ten thousand years.

日本的寶永山是一座死火山,已經超過一萬年沒有噴發。

extinct volcano + named example + time since eruption

The trail led the group up the cone of an extinct volcano to a crater filled with rainwater.

步道帶領隊伍登上死火山的錐狀山頂,來到一個積滿雨水的火山口。

同義詞
  • inactive

    broader term that also covers dormant volcanoes; does not carry the same finality as extinct

  • dead

    informal equivalent for extinct volcano

反義詞
  • active

    currently erupting or likely to erupt

  • dormant

    temporarily inactive but could erupt again

文法句型

extinct + volcano

用法筆記

Used almost exclusively to modify the noun volcano. Do not confuse with dormant — a dormant volcano could erupt again, while an extinct volcano cannot.

常見錯誤

Mount Vesuvius is an extinct volcano.
Mount Vesuvius is a dormant volcano.
💡Vesuvius erupted in 1944 and could erupt again, so it is dormant, not extinct.

3.形容詞C1
釋義

火焰或燈火已完全熄滅

例句

Élise knelt by the fireplace and blew on the coals, but the fire was extinct and would not catch.

Élise 跪在壁爐旁對著煤炭吹氣,但火已經熄了,無法再燃起。

When the firefighters arrived, the blaze had burned itself extinct, leaving only blackened timber.

消防人員抵達時,大火已經自行燒盡熄滅,只留下焦黑的木頭。

burned itself extinct + remains of fire

同義詞
  • out

    everyday word for a fire or light that is no longer burning

  • dead

    informal; a dead fire has no remaining heat or flame

反義詞
  • alight

    burning or glowing

  • lit

    illuminated or burning

文法句型

be + extinct

burn + extinct

用法筆記

In modern everyday English, the adjective extinct for fire has largely been replaced by out or dead. Using extinct in this sense sounds literary or old-fashioned and is uncommon outside novels and historical writing.

常見錯誤

The campfire is extinct, let us light another one.
The campfire is out, let us light another one.
💡out is the natural choice in everyday speech; extinct sounds overly formal.
