Edward Steere,
Some account of the town of Zanzibar
(1869)
“ One result of all this is too important to be passed by in silence, it is that the language of Zanzibar—the Swahili—being the official and the trade language, is everywhere more or less understood, so that whereas if you learnt one of the up-country languages you would be a stranger everywhere else, if you have well mastered the Swahili you are at home everywhere, in every tribe you will find some who can act as interpreters, and who can at once open to you the intricacies of their own tongue. ”
