Unannounced means happening with no warning — nobody was told it was coming.
Its most common use is about people arriving: 'He turned up unannounced.' Here it works like an adverb, sitting after the verb, and it usually carries a small feeling — surprise, sometimes , because in most cultures you are expected to say you are coming. An unannounced visit, an unannounced guest, an unannounced inspection.
That inspection use is worth knowing on its own. Health inspectors, safety officers and auditors do unannounced checks on purpose, so that nobody can tidy up first. So the word can carry a hint of 'and that was the point'.
It also works for events and decisions: 'The change was made unannounced', 'an unannounced product'. In the tech world, an unannounced phone is one the company has not yet admitted exists.
A thing students miss: unannounced says nothing about whether it was PLANNED. An unannounced inspection is carefully planned — it just was not told to you. It is about the telling, not the planning.
組成un-（沒有）+ announce（宣布）+ -ed（被…的）。announce 來自拉丁文 annūntiō：ad-（朝向）+ nūntius（信使、消息）——把消息送到人面前。

unannouncedadj

Not announced beforehand.
- But soon one notices, first in ones and twos, and then in larger groups, men who are very much alive at this hour in the morning, the sorters for the Caledonian, and Edinburgh sections of the "Down Special"; mail is piled high on the platforms, and the postal men glance occasionally towards the platform intermediate signals. By this time the calling-on arm is pulled off, and a few minutes later in comes the train, unannounced by the loud-speakers, to the mystification of many travellers.
- In 2008, she was at times criticized for being detached from voters, insulated in a bubble of staff and security and avoiding spontaneity.
