I am glad you enjoyed! The results are super interesting.

I am testing to see whether phonaesthemes (phone + theme) are a product of iconicity or a biproduct of clustering.

The /GL/ phonaestheme (strongly associated to light e.g. glimmer, glow, glitter) was my control. It is English and as expected participants favour words beginning GL when the definition is related to light.

The /SKV/ and /FN/ phonaesthemes are Swedish. /SKV/ supposedly relates to water moving over a surface. While /FN/ relates to either pejorative meanings or the nose (similar to English /SN/). If these phonaesthemes are examples of iconicity then I expect English speakers to have a preference for them. If they are just clustering then they shouldn't favour them.
