1
permanent dying out of a species
The complete death of a kind of animal or plant, so that none are left alive in the world.
Vartosenos šablonas:
the extinction of [a species/group]
Dažna klaida:
Learners sometimes confuse "extinction" with "instinct" because they sound similar, but they are unrelated: "extinction" is about disappearing completely, while "instinct" is a natural behavior. Another mistake is to say *"an extinction of tigers"* for one species; in most cases we say *"the extinction of tigers"* or *"tiger extinction" unless we are talking about several different extinctions.
Sinonimai
die-off (Often used in science and news for a large, sudden loss of animals or plants; slightly more informal.)
|
wiping out (More informal and emotional, often stressing that humans caused the extinction.)
Antonimai
survival (Focuses on a species continuing to live instead of disappearing completely.)

disappearance of a custom or group
The slow end of a way of life, a language, or a group of people until it does not exist anymore.
Vartosenos šablonas:
the extinction of [something abstract]
Dažna klaida:
Learners sometimes overuse this sense with things that normally just "end" or "stop". For example, we usually say *"the end of the meeting"* rather than *"the extinction of the meeting"*. Use "extinction" when something disappears completely and permanently, not just when it finishes.
Sinonimai
disappearance (General word; does not always suggest a slow, final ending the way "extinction" does.)
|
dying out (More informal; often used for traditions or languages fading away over time.)
Antonimai
revival (Emphasizes bringing something back into active use after it was close to disappearing.)

loss of a learned response
In psychology, when a learned action slowly stops happening because it is not rewarded or repeated anymore.
Vartosenos šablonas:
the extinction of [a learned/conditioned response]
Dažna klaida:
Learners may confuse psychological "extinction" with everyday "forgetting". In psychology, extinction is about change in learned connections between stimulus and response, not simply losing a memory.
Sinonimai
unlearning (Informal and less precise; used in everyday speech rather than scientific writing.)
Antonimai
conditioning (Refers to the process of creating or strengthening a learned response, rather than making it disappear.)

reduction of light intensity
In physics, when light or other energy becomes weaker as it moves through air, glass, dust, or another material.
Vartosenos šablonas:
the extinction of [light/radiation] in/through [a medium]
Dažna klaida:
Learners may wrongly apply the biological meaning here and think of species dying out. In technical physics texts, "extinction" usually refers to radiation intensity becoming weaker, not to living things.
Sinonimai
attenuation (Standard technical term in physics and engineering; not limited to light and often broader than "extinction".)
Antonimai
transmission (Focuses on radiation passing through a medium without being significantly reduced.)

ending of a right or obligation
In law, when a right, claim, or debt officially ends and does not exist anymore.
Vartosenos šablonas:
the extinction of [a right/debt/obligation]
Dažna klaida:
Learners may try to use this legal sense in everyday situations where simpler words like "end" or "finish" are better. Use this meaning mainly in legal or financial writing.
Sinonimai
termination (Common in everyday and legal English; slightly broader, can mean ending of many kinds of agreements or situations.)
Antonimai
creation (Refers to bringing a right or obligation into existence, rather than ending it.)
