Sound and phonetics in 1836: Humboldt on sound

Does a harsh-sounding name make a harsh person? No. Listeners may attach metaphors to sounds. That is their poetry, not a developmental law. Across many languages, people tend to match a rounded nonce word to a rounded shape and a spiky word to a spiky shape — a famous sound-symbolism demo.

Lieberson noted that parents copy the feel of neighbouring names. Shared endings (-en, -a, -son) are phonetic fashion, visible in SSA and ONS series. Is an “unpronounceable” name objectively hard? Hard for whom? Phonotactics are language-specific. English clusters can be easy in Polish and vice versa.

Do brands use sound symbolism on purpose? Yes — brand-naming often tests vowels and voiced consonants. That is marketing craft, still not destiny. Can phonetics explain Emily vs Lakisha callbacks? Only as a small fluency factor. Bertrand and Mullainathan’s gap is primarily about racialised inference, not syllable difficulty.
