Not legally acceptable or in force
Not officially or legally OK, so it cannot be used or accepted.
Vartosenos šablonas:
[something] is invalid
Dažna klaida:
Learners sometimes say 'illegal' when they mean 'invalid'. 'Illegal' means against the law; 'invalid' means something has no legal or official effect, which may or may not be a crime. Another mistake is using 'not correct' instead of 'invalid' when talking about documents, tickets, or contracts that are not accepted.
Sinonimai
void (More legal-sounding; very common in contracts and formal documents.)
|
not valid (More everyday and direct; less formal than 'invalid'.)
Antonimai
valid (Means legally or officially acceptable and in force.)
|
binding (Stresses that something must be obeyed because it has legal force.)

Not logically or factually sound
Not based on good logic or true facts, so the idea or argument should not be accepted.
Vartosenos šablonas:
an invalid [argument/claim/criticism/assumption]
Dažna klaida:
Learners sometimes confuse 'invalid' with 'false'. A statement can be false but still logically valid inside an argument, and an argument can be invalid even if its conclusion happens to be true. Outside formal logic, many speakers just use 'invalid' to mean that an argument is not acceptable, so learners do not need to master the strict logical use at first. Also, do not use 'invalid' to describe people; that use is old-fashioned and offensive.
Sinonimai
flawed (Suggests a mistake or weakness; less formal and less strictly logical than 'invalid'.)
|
unsound (Common in academic or formal criticism; stresses weak or wrong reasoning.)
Antonimai
valid (In this context, means logically correct or well supported by facts.)
|
sound (Emphasizes that the reasoning is solid and reliable.)

Not accepted by a system
Not accepted by a computer or system because it is written wrongly or does not follow the rules.
Vartosenos šablonas:
invalid [password/input/code/email address]
Dažna klaida:
Learners sometimes think 'invalid password' means the password no longer exists. Often it simply means the password you entered does not match what the system has saved. Also, 'invalid' is preferred over 'wrong' or 'not correct' in on‑screen messages and technical writing.
Sinonimai
incorrect (More general; does not always mean that a system rejects it, only that it is not right.)
|
unacceptable (Stresses that the system or process will not allow it.)
Antonimai
valid (In computing, means formatted correctly and accepted by the system.)
|
recognized (Emphasizes that the system knows and accepts the input.)

Person very sick or disabled
An old word for a person who is very sick or disabled for a long time and cannot care for themselves. It is now considered rude.
Vartosenos šablonas:
an invalid
Dažna klaida:
Learners sometimes think 'invalid' is a normal, modern word for a disabled person and use it in everyday speech. In current English, this is old-fashioned and often offensive. Use 'disabled person', 'a person with a disability', or a more specific description instead.
Sinonimai
disabled person (Modern and neutral; focuses on the person, not only the illness.)
|
patient (A person receiving medical care; does not always mean long‑term or severely disabled.)
Antonimai
