Not sealed; open or having had a seal removed; accessible or not kept secret.
Compound of the prefix 'un-' (Old English, meaning to reverse an action) plus 'sealed' (from 'seal,' via Old French from Latin 'sigillum,' meaning mark or seal). This compound emerged in Middle English.
The prefix 'un-' is one of the most productive in English—you can stick it on almost any adjective and get its opposite, which is why English speakers can be so creative with language! 'Unsealed' is perfect because it captures the moment when something that was closed gets opened.
