Wheeler's Orthoepic Rules • The Sound /f/ in GH and PH

1. 1. Germanic Sound Shift of GH: In Old English, gh was a guttural sound (/x/). By the 16th century, in certain words it shifted to a labiodental /f/ (laugh, tough, rough, cough, enough).

2. 2. Greek Digamma & PH: Words from Greek containing the letter phi (Φ) were transcribed by the Romans as ph, representing /f/: phantom, phrase, photograph, telephone, orphan.

3. 3. Draught vs. Draft: draught is the historical British/classical spelling for a drink or current of air, pronounced identically to modern draft (/drɑːft/ or /dræft/).
