Sense: adjective/1
These words all suggest that something has not been fully dealt with, but they focus on different stages. 'Unread' is specific to writing or messages and means the words have not yet been taken in. 'Unopened' comes earlier: a letter can be unopened before anyone even looks inside, and it may remain unread after opening. 'Ignored' adds intention, suggesting someone chose not to pay attention. 'Unseen' is broader and often visual, so an unseen alert may simply never have appeared on the screen. Use 'unread' when the important fact is that the written content itself still has not been read.
Etymology
Formed in English from the negative prefix 'un-' and the past participle 'read'. The basic adjective sense simply means 'not yet read'. In modern digital use, it also developed a noun sense for messages or notifications that still wait in an inbox or chat list.
