What does backdated mean?
Backdated describes something — a document, contract, payment, or decision — that has been assigned a date earlier than the one on which it was actually made or approved. The term arises most often in administrative and financial contexts: a pay rise may be backdated so that employees receive arrears from an earlier point, or a benefit claim may be backdated to cover a past period. In these everyday uses the word is neutral and even welcome, signalling that someone is being compensated retroactively. Elsewhere, however, backdating carries a darker shade of meaning, since deliberately dating documents falsely can amount to fraud, as in the corporate scandals involving executives who backdated stock option grants to maximise their value. The word derives from the verb backdate, itself built on the noun 'date', which traces through medieval Latin to the classical Latin dare, 'to give'.

Etymology of backdated
'Backdated' is the past participle of 'backdate', a compound formed in modern English by combining the adverb 'back' with the verb 'date'. The word 'date' ultimately descends from the Latin phrase 'datum', meaning 'given', the past participle of 'dare', 'to give' — the same root that gives us words like 'data', 'donate', and 'dose'. The practice of assigning earlier dates to documents is ancient, but the compound 'backdate' itself emerged in English only in the nineteenth century.
