I've always gone with "an HTML file" or "a .html file". A quick straw poll here had most people not aspirating the "h". They all said: "An aitch Tee Em Ell file" :) Apropos of nothing, though. I have no hard and fast rule to back that up. Amanda From: robert@xxxxxxxxxxxxxxxxxxxx To: austechwriter@xxxxxxxxxxxxx Subject: atw: Haitch or Aitch? Date: Thu, 5 Jan 2012 12:47:38 +1100 I’m editing a doc where the writer referred to “a HTML file.” Both haitch and aitch pronunciations are permitted in Macquarie (though haitch is first). This has probably come up many times on this list, but I don’t remember it… The Cambridge Guide to Australian English Usage says that a survey in 2000 found that: “43% of younger people (under 25 years) were prepared to say that they used “haitch”, but only 6% of those 65 and over.” Any thoughts? rwl
