Ff

• (standard) IPA^(key): /ɛf/
  • (informal) IPA^(key): /f(ː)/

Ff (upper case, lower case ff)

1. The ninth letter of the Welsh alphabet, called èff and written in the Latin script. It is preceded by F and followed by G.

Like the other Welsh digraphs, Ff is considered a distinct letter of the Welsh alphabet for all purposes, including collation. Thus, Ffrainc is alphabetically sorted after Fietnam.

• Ff cannot be mutated in Welsh.
