What does initialled mean?
“Initialled” describes something that has been signed or marked with a person's initials. It is especially common in formal contexts, such as contracts, manuscripts, forms, and official records, where a signature may be unnecessary but initials provide evidence that the responsible person has seen, approved, authenticated, or completed the item. As a verb, “initialled” is the past tense and past participle of “initial”; as an adjective, it describes an item bearing such a mark. The expression can also refer to initialling a document without implying full agreement with every detail, although context often makes approval the intended implication. British English normally uses the spelling with two l's, while American English generally writes “initialed.” The word is useful in legal, administrative, editorial, and historical contexts, where the precise status and handling of documents matter.

Where does initialled come from?
The word is formed from “initial,” originally derived from Latin initialis, meaning “of or belonging to the beginning,” from initium, “beginning” or “entrance.” Adding the English suffix “-ed” creates the past tense and participial forms “initialled” and “initially marked.” Related English words such as “initiate,” “initiation,” and “initiative” come from the same Latin root.
