"Kladivo na čarodějnice" (in czech) or "Malleus Maleficarumis" (in latin) is a title of czech novel translated as Witches' Hammer or Witchhammer. Hammer on Witches is the name of book (manual) used in this novel to seek out and eradicate witches.
Is the phrase "Witchhammer" understood by native English speaker as phrase with hidden meaning?
For example like hidden meaning when we imagine the situation of two guys listening radio news on politics and one guy say to another: "This senator speaks again in Orwellian language?" (hint of 1984 book - angsoc, face-crime, double-think etc.)
Orwellian language - not telling the TRUE names
Kladivo na čarodějnice - to use effective handbook (full of effective and cruel methods) for solving the problem ruthlessly
