1
no longer existing as a species
No longer living anywhere, because all animals or plants of that kind have died.
Padrão de uso:
[species/kind] is extinct
Erro comum:
Learners sometimes use 'extinct' for individual animals or people, saying things like *'My cat is extinct.'* This is incorrect. Use 'extinct' only for whole species or types, not for single living things. For an individual, say 'dead'. Learners also confuse 'extinct' with 'distinct'; 'distinct' means 'clearly different'.
Sinônimos
died out (More informal, usually used as a phrasal verb rather than an adjective.)
|
gone (Very general and informal; does not specifically refer to species or biology.)
|
lost (Suggests something that has disappeared, but is broader and less precise than 'extinct'.)
Antônimos
endangered (Describes a species that is at high risk of extinction, not yet extinct.)
|
thriving (Emphasizes that a species is doing very well, the opposite of having died out.)

2
no longer used or active
No longer in use or no longer happening, because it has died out or stopped completely.
Padrão de uso:
[practice/technology/job] is extinct
Erro comum:
Learners sometimes use 'extinct' too broadly, for example *'My old phone is extinct.'* For single objects that you can still find or that only you stopped using, 'old' or 'outdated' is better. Use 'extinct' when a whole type, practice, or language has disappeared or completely stopped.
Sinônimos
obsolete (Common for technology and tools; suggests something has been replaced by something newer.)
|
defunct (More formal; often used for organizations, businesses, or systems that no longer operate.)
|
outdated (Still exists but no longer modern or preferred, weaker than 'extinct'.)
Antônimos
current (Stresses that something is used and belongs to the present time.)
|
widespread (Highlights that something is common and active in many places.)

of a volcano, no more eruptions
Used about a volcano that will not erupt again because its activity has stopped.
Padrão de uso:
[volcano] is extinct
Erro comum:
Learners often confuse 'extinct' and 'dormant' for volcanoes. 'Dormant' means it is not erupting now but could in the future; 'extinct' means it is not expected to erupt again.
Sinônimos
inactive (General and less precise; can mean simply not active now, not necessarily forever.)
|
dormant (A volcano that is sleeping and may erupt again; not as final as 'extinct'.)
Antônimos
active (A volcano that is currently erupting or shows clear signs it may erupt.)

|
