Usage

In the past diphtheria was pronounced with an f sound representing the two letters ph (as in telephone, sulphur, and other ph words derived from Greek). In recent years the pronunciation has shifted and today the most common pronunciation, no longer incorrect in standard English, is with a p sound. A very similar shift has taken place with the word diphthong, which is now also widely pronounced with a p rather than an f sound

Origin

Mid 19th century: modern Latin, from French diphthérie (earlier diphthérite), from Greek diphthera ‘skin, hide’.
