ability of something to work
The chance that a plan, idea, or project can really work well in the real world.
用法パターン：
the viability of [something]
よくある間違い：
Learners sometimes confuse "viability" with "vitality." "Viability" is about whether a plan, idea, or project can work or succeed; "vitality" is about energy or liveliness. Another common mistake is using it without the usual pattern; it is most natural to say "the viability of [something]" rather than just "the viability" by itself.
類義語
feasibility (Very close in meaning; slightly more common in everyday business English and does not strongly suggest long‑term success, just possibility.)
|
workability (More informal and concrete; often used when talking about whether something can be used or done in practice.)
|
practicability (Slightly more formal and less common; focuses on whether something can realistically be put into practice.)
対義語
infeasibility (Direct opposite, meaning that something cannot be done or cannot succeed in practice.)
|
impracticality (Stresses that something is not sensible or realistic to use in real life, so its viability is low or zero.)

ability of living things to survive
The ability of a cell, embryo, seed, or other living thing to stay alive and keep growing under certain conditions.
用法パターン：
the viability of [cells/embryos/seeds]
よくある間違い：
Learners may mix this biological meaning with the more general idea of a plan being viable. In biology and medicine, "viability" refers specifically to living things (cells, embryos, seeds, populations), not to projects or ideas. Context words like "cells," "embryos," "seeds," or "fetal" usually signal this technical sense.
類義語
survivability (Very similar, but can be broader; often used for organisms or systems in difficult conditions, not only in lab or medical contexts.)
|
capacity to survive (A descriptive phrase rather than a single word; slightly less technical but expresses the same basic idea.)
対義語
nonviability (Technical opposite meaning that cells, embryos, or organisms cannot live or develop.)
|
mortality (Focuses on death rate rather than ability to live, but is often contrasted with viability in medical and biological contexts.)
