unpenetrated
Still holding firm
Unpenetrated means not entered, pierced, or passed through.
The term applies literally to physical barriers: unpenetrated armor, unpenetrated wilderness.
It extends to abstractions—an unpenetrated mystery remains unsolved, an unpenetrated market hasn't been entered by competitors.
The word sometimes carries sexual connotations, describing a body not yet entered.
