the words for 'sea' consistently depend upon continuant consonants, while the words for 'earth' or 'ground' depend upon plosive consonants... The sea as we move over or through it does not involve an obstruction of movement; whereas the earth or ground, at least insofar as it breaks a fall, always does.
Abram presents cross-linguistic evidence that consonant type — continuant versus plosive — is motivated by bodily and elemental experience, grounding phonological form in phenomenological reality.
