'Invalid' means not valid or legally binding; it can also mean someone who is ill or disabled, though the first definition is far more common. Think of a fake ID 🆔 that won't get you into a club, or a password 🔑 that doesn't work for your account. It lacks legal or factual force. Unlike something that's valid, an invalid item cannot be accepted or used. It implies a flaw or defect that makes it unacceptable. Generally applies to information or authorisation.
'Invalid' comes from the Latin word 'invalidus,' meaning 'not strong, feeble, infirm.' It's formed from 'in-' (not) and 'validus' (strong, effective). The term originally referred to physical weakness. Over time, it extended to mean 'not legally valid' or 'without factual basis,' retaining the sense of lacking strength or effectiveness.
