logical or factual soundness
The quality of an idea or argument being correct because it follows logic and facts.
用法模式：
the validity of [a claim/argument/method]
常见错误：
Learners often confuse "validity" with "truth" or "value". Something can have validity in its reasoning even if some details are later shown to be wrong. Another common mistake is using "validity" where the adjective "valid" is needed, e.g. saying *"This is a validity argument" instead of "This is a valid argument." Also, "validity" is almost always uncountable; avoid forms like *"many validities" in general English.

legal force or effectiveness
The quality of something, like a contract or law, being accepted by the law and having legal power.
用法模式：
the validity of [a contract/law/decision]
常见错误：
Learners sometimes mix up "legal" and "valid" and say *"this contract is legal" when they mean "this contract has legal validity" or "this contract is valid." "Legal" can mean simply "not against the law," while "validity" refers to whether a document or act fully works in law (for example, whether a contract can be enforced).
近义词
legality (Focuses on being allowed by law in general, while "validity" focuses on having full legal effect.)
反义词
illegality (Describes something that is not allowed by law and therefore lacks legal validity.)

period something remains valid
The time period when something, like a ticket or passport, can still be used and is accepted as valid.
用法模式：
the validity of [a ticket/passport/visa]
常见错误：
Learners sometimes say *"How long is this ticket valid for its validity?" Instead, ask "How long is this ticket valid?" or "What is the validity of this ticket?" Another mistake is confusing "validity" with "availability"; a product can be available in a shop even if its warranty validity has ended.

expiry (Refers to the end of the period when something has validity.)

reasonableness of feelings or concerns
The quality of a feeling or worry being sensible and something that people should respect.
用法模式：
the validity of [someone’s feelings/concerns]
常见错误：
Learners sometimes overuse words like "right" or "true" instead of "validity" in emotional contexts, saying "my feelings are true" when they mean "my feelings have validity" or "my feelings are valid." Also, "validity" here does not mean that the facts are correct; it means the emotional reaction is understandable and deserves respect.
近义词
legitimacy (Emphasizes that something deserves respect or recognition, not just that it follows logic.)
反义词
unreasonableness (Describes feelings or concerns that are seen as not sensible or not deserving serious attention.)

用法模式：
the validity of [a test/measure/study]
