It was not until the XNUMXth century that the word From takes on the meaning we know it today, namely a table or a stone slab.
But previously, in the XNUMXth century, it had the meaning of channel, gutter, sink, trough or basin. It is borrowed from the old Norman daela, of the same meaning. And it is from this meaning that in the XNUMXth century, the word, in slang version, designated the throat, this "channel" through which drinks and food pass, a meaning which also gave the expressions rinse the slab ou have a sloping slab (which should not be confused with our to be hungry).
To be hungry dates from 1960, it seems (at Auguste le Breton). It is an attenuation of break the slab, which dates from the same period and which is a mixture of Starve with this famous From on which the food slides.
The expressions “Rinse the slab - Have the slab on a slope”: Drink - Drink often (alcohol).
In the XNUMXth century, From is borrowed from the old Nordic daela which means "sink (kitchen", but also "channel" or "gutter".
It is these last two meanings which, in the XNUMXth century, gave birth to the metaphorical meaning of "throat", the latter finally being able to be considered only as a channel which directs the liquid towards the stomach.
Despite the age of the metaphor, these two expressions did not come into existence until the XNUMXth century.
In the same era, to drink also said to himself rinse the corridor.
Note that rinse the slab can be used for any drink, including the flattest possible water, and even in small quantities, while have a sloping slab applies to heavy drinkers of alcoholic beverages.
