What do “a pinch of salt” and “a grain of salt” mean in English?

To take something with a grain of salt or a pinch of salt means not to take it too seriously or too literally.

It is mostly used in relation to a piece of information, comment or advice.

The saying is slightly ambiguous in that it can be understood in one of three different ways.

  1. The grain or pinch of salt can refer to a small amount of regard with which something should be taken.
  2. However, it can also be thought to refer to Roman author, Pliny The Elder’s, belief that salt was an element in an antidote to poison. (In this case, the comment would be the poison).
  3. There is also the version that at the time salt was used to assist in the consumption of poison. (Here again, the comment would be the poison).
