pincette : noun Small instrument made up of two branches for picking up small objects such as sugar cubes.
To be taken with tweezers: with great caution.
Not to be taken with a grain of salt: being in a very bad mood.
The expression “Not to be taken lightly”: To be very dirty, repulsive, despicable, despicable – To be in a very bad mood.
When the word tweezers appeared a few centuries ago, it designated a small tweezers and a two-pronged metal instrument for moving logs and embers in the fire, without getting burned.
The tweezers used in the fireplace therefore made it possible, in a broad sense, not to grasp something directly, as would be the case of someone who would be repulsive because of deplorable hygiene.
It is from this image of something that one avoids touching that the expression appeared at the beginning of the XNUMXth century with the first meaning indicated. And it was in the middle of the same century that the custom of speaking of a very angry person appeared, who obviously should only be approached, touched, with the utmost care.
