Unencrypted is the broadest and most common term for data that lacks encryption protection. Plaintext is a precise technical term used in cryptography for data before encryption or after decryption — it is not a general synonym for 'unprotected'. Uncoded sounds slightly old-fashioned and is rarely used in modern computing. Clear appears in phrases such as 'clear text' but is ambiguous because it can also mean easy to read or see-through. In everyday security discussions, use unencrypted (e.g., 'unencrypted connection', 'unencrypted file'); in cryptographic contexts, use plaintext ('the plaintext is fed into the encryption algorithm').

Etymology
Formed by adding the prefix un- (meaning 'not') to 'encrypted', the past participle of 'encrypt'. The verb 'encrypt' was first recorded in English around the 1940s and comes from the Greek word 'kryptos', meaning 'hidden'. The term became widely used with the rise of digital computing and internet security.
