the linguistic sign is not arbitrary!
I’ve been researching the Bouba/kiki effect more in depth.
One of my most surprising finds is that the linguistic sign is not (always) arbitrary, contrary to what de Saussure said about 100 years ago[1] and which is still held as a fact.
The image shown comes from the English translation of Cours... by de Saussure.
Huh!
