Alfred Hitchcock’s comedy-thriller The Trouble with Harry (1955), amidst all its talk of murder and romance, has a fun little exchange of sociolinguistic interest between John Forsythe (‘Sam Marlowe’) and Edmund Gwenn (‘Capt. Albert Wiles’):
Idries Shah’s 1964 book The Sufis, which I read over the holidays, has several interesting passages on language, a couple of which I quote below. The first excerpt concerns the history and use of the protean word Sufism and some of the various terms used to refer to Sufis:
Exactly how old is the word “Sufism”? There were Sufis at all times and in all countries, says the tradition. Sufis existed as such and under this name before Islam. But, if there was a name for the practitioner, there was no name for the practice. The English word “Sufism” is anglicized from the Latin, Sufismus; it was a Teutonic scholar who, as recently as 1821, coined the Latinization which is now almost naturalized into English. Before him there was the word tasawwuf – the state, practice or condition of being a Sufi. This may not seem an important point, but to the Sufis it is. It is one reason why there is no static term in use among Sufis for their cult. They call it a science, an art, a knowledge, a Way, a tribe – even by a tenth-century portmanteau term, perhaps translatable as psychoanthropology (nafsaniyyatalinsaniyyat) – but they do not call it Sufism.
