Other forms: minefields
A minefield is ground sown with explosives, or a matter full of hidden dangers. Clear the minefield, a legal minefield, a political minefield.
The literal ones outlast the wars that laid them by decades, and clearing is slow, dangerous work. The figurative sense is now the commoner: a legal minefield is a subject where the danger is not visible until you step on it.
