Spelling of Sulfate (not Sulphate?)
There has been some debate and protest about the spelling of the word ‘sulphur’ and the apparent trend to spell it as ‘sulfur’. The debate and protest is not confined to Australia and is going on in many countries.
Much of the variation in spelling arises from scientific spelling as opposed to usage in day to day literature. About 20 years ago, the International Union of Pure and Applied Chemistry (IUPAC), the equivalent of a ‘United Nations’ of world chemistry, and other scientific organisations adopted the ‘sulfur’ form. For scientific correctness, most scientists have followed this form. The Australian journals of science have also adopted this spelling.
As outlined below in a segment quoted from Wikipedia, sulfur is a word of Latin origin and late Latin used the ‘f’ form of the word. The ‘ph’ spelling to denote the ‘f’ sound is of Greek origin, hence the spelling of the Greek ‘phosphorus’.
Really it boils down to choice, but it is likely that scientists in Australia will increasingly use ‘sulfur’ and this spelling will be taught in school science. Non-scientists can probably use what spelling they like, but should accept that scientists will use the recommended form, if only because the journals they publish in follow the IUPAC decision.
To quote from Wikipedia Sulfur Spelling and Etymology :
The element has traditionally been spelled sulphur in the United Kingdom, most of the Commonwealth including India, Malaysia, South Africa and Hong Kong, along with the rest of the Caribbean and Ireland, but sulfur in the United States, while both spellings are used in Australia, New Zealand and Canada. IUPAC adopted the spelling “sulfur” in 1990, as did the Royal Society of Chemistry Nomenclature Committee in 1992 and the Qualifications and Curriculum Authority for England and Wales recommended its use in 2000.
In Latin, the word is variously written sulpur, sulphur, and sulfur (the Oxford Latin Dictionary lists the spellings in this order). It means brimstone. It is an original Latin name and not a Classical Greek loan, so the ph variant does not denote the Greek letter φ. Sulfur in Greek is thion (θείον), whence comes the prefix thio-. The simplification of the Latin word's p or ph to an f appears to have taken place towards the end of the classical period, with the f spelling becoming dominant in the medieval period.
To quote from the Nature journal article 'so long sulphur':
Language is our servant, not our master and it evolves to meet our needs. And in the case of sulfur, there seems to be no good reason to continue using the 'ph' form other than perhaps a mistaken sense of spelling jingoism.
