The story of Demetrious
Metathesis, the swapping of two adjacent sounds or letters, is a regular process in English and it has produced a good deal of the modern vocabulary. Bird was brid in Old English; horse was hros; third was thridda; wasp was waeps. Ask and aks have been alternating for a thousand years and both appear in medieval texts. Names undergo the same thing, and respelling accelerates it because the writer is working from sound rather than from a remembered spelling. Demetrious is not a random error: it lands on a sequence English uses constantly, since -ous is one of the language's most productive adjective endings. The respelling therefore moves the name from an unfamiliar Latin pattern to a familiar English one, which is what most respellings do even when nobody involved could describe the process.
Meaning
Greek Demetrios, of Demeter
From Demeter, the Greek goddess of grain, whose own name is only half explained: meter is mother and the first element is disputed. Demetrios means belonging to Demeter and was one of the commonest Greek personal names. Demetrious is an American respelling of Demetrius with the final vowels transposed, and carries no separate meaning. It peaks in 1971.
