Semitic languages like Arabic use consonantic roots conveying meaning, like ktb which is related to writing. The vowels to be added to form a word vary and give a nuance to this general meaning. Similarly, phonosemantics states that some sounds convey a meaning by themselves. It's striking to notice that languages as different from one another as Japanese, cauchois (patois spoken in pays de Caux, normandy) or German share similarities in the respective verbs meaning "to walk", namely aruku, arquer and walken. The global shared structure is a-r/l-k as sounds, which as such seem to convey the same overall meaning. One can draw a parallel with genetics, where genes are divided into coding parts, namely exons, and non coding parts, namely introns. The mechanism of alternative splicing of introns allows the same gene to code for different proteins, a bit like the ktb example above, where the consonantic root coresponds to exons, and vowels to introns.
So I would like to know if one can generalize these phenomena defining the abstract notion of semainophoric (from ancient Greek semaino=to mean, to bear a signal) structure appearing in morphology, as some kind of skeleton conveying meaning, nuances thereof being the flesh and organs over it. Has this been considered so far?
