IPA: /ʌnˈsʌŋk/
KK: /ʌnˈsʌŋk/
Describing something that has not been submerged or brought down into water.
The ship remained unsunk despite the stormy weather.
Unsunk → It is formed from the prefix "un-" (meaning not) and the root "sunk" (the past participle of "sink", which comes from Old English "sincan", meaning to go down or descend). The word "unsunk" means not having sunk or not being submerged.
Think of 'not' ('un-') having 'gone down' ('sunk') — that's why unsunk means something that has not sunk.
