IPA: /ˌʌn.kənˈsiːld/
KK: /ʌnˈkənˌsiːld/
Not hidden; clearly visible or obvious.
The unconcealed truth was hard for everyone to accept.
Unconcealed → It is formed from "un-" (meaning not) and "concealed" (from Latin "celare", meaning to hide). The word "unconcealed" means not hidden or made visible.
Think of 'not' ('un-') hiding something ('celare') — that's why unconcealed means something that is visible or revealed.
