Usage Note

Almost always appears inside the fixed expressions 'keep someone posted' (active informing) and 'stay posted' (continual receiving of news). You cannot say 'I posted him on the news' — the verb 'keep' or 'stay' is required.

Common Mistakes

Please post me on the meeting results.
Please keep me posted on the meeting results.
'posted' as an adjective needs 'keep', 'stay', or 'be' before it; it cannot replace the verb 'post'.
I am posted about the situation.' (used alone)
I am posted on the situation.' or 'Please keep me posted about the situation.
When used with 'am', the preposition is usually 'on', and the expression is still less common than 'keep me posted'.

Sense: adjective/1

All four words describe knowing the latest information, but they differ in usage patterns and register. 'Posted' is the most restricted — it almost always needs the helper verb 'keep' or 'stay' ('keep me posted'), and it is informal. 'Informed' is more formal and versatile: you can say 'keep me informed,' 'I am well informed,' or 'an informed opinion.' 'Updated' leans toward digital and project-management contexts ('keep me updated on the ticket status'), and is common in workplace email. 'Up-to-date' is a standalone adjective that can appear anywhere in a sentence ('I am up-to-date,' 'the most up-to-date report'), making it the easiest to use. For casual requests, 'keep me posted' and 'keep me updated' are interchangeable, but 'keep me informed' sounds more serious or official.

Etymology

LatinFrenchEnglish

The adjective 'posted' comes from the verb 'to post,' meaning to place or affix in a public spot. The sense of being 'posted on a matter' originated from the idea that someone whose name was on a mailing list or posted in a public notice would receive all the latest news. Over time, the phrase 'keep someone posted' grew into a common expression for sharing current information.
