We do not need to borrow words from the learned. That, I suppose, is a lesson that any anthropologist and historian must learn. Those whom we represent don't need to borrow the words of the learned to say who they are. Their words are never-endingly subtle and manifold. The crudities and sparsities are ours, the translators, as we give their words typologies and grammar.
Talk is never bare words, of course.
It is all the ways words are symbolised. It is voice and gesture, rhythm and timing, colour and texture. Talk is tattoo. Talk is body paint and house columns. Talk is never just stream of consciousness either.
