Dolfin or Dolphin – Quick Answer

The Origin of Dolfin or Dolphin

The English word dolphin has a long history.

It comes from the Latin word delphinus, which was borrowed from the Ancient Greek word delphis. As the word moved through French into English, the spelling changed but kept the ph, reflecting its Greek roots.

Because ph produces the /f/ sound, many people assume the word should be written as dolfin. While that spelling matches pronunciation, English has kept the historical spelling dolphin.

Examples of other English words with the same pattern include:

Phone
Pharmacy
Photograph
Philosophy
Elephant

Although they sound like they contain the letter f, they are correctly spelled with ph.
