What does undated mean?
Undated means that something bears no date or has not been assigned one. The adjective is commonly applied to letters, manuscripts, photographs, inscriptions, coins, archaeological specimens, and historical records whose exact date is unknown or unrecorded. Saying that an object is undated does not necessarily mean that it is old; it means only that no date is supplied or known. In a catalogue, for example, an undated photograph might still have been taken recently, while an undated manuscript could be centuries old. The word is also sometimes used more broadly for contracts, agreements, and other records lacking a date, although a legal or administrative context may distinguish an undated item from one that is merely undated in its visible form. Undated is useful because it identifies a specific absence without implying a date, age, authenticity, or historical period that the evidence does not establish.

Where does undated come from?
Undated was formed in English by combining un- with date, meaning to assign a date or specify when something occurred. Date itself comes through Old French from Latin datum, meaning given, with the sense of a day or period assigned to an event. The same Latin root underlies English datum and its plural data, while dateless is a closely related English formation.
How undated is actually used
The term is neutral in register and is especially common in reference work, archives, publishing, history, archaeology, and genealogy. It usually describes a document or object rather than a person or place.
