|Unicode name||ARMENIAN SMALL LETTER FEH|
Introduced in the 11th century (first attested in 1037). Probably modeled on Ancient Greek φ.
ֆ lowercase (uppercase Ֆ)
- The 39th and last letter of Armenian alphabet, called ֆե (fe). Represents voiceless labiodental fricative: IPA: [f]. Transliterated as f.
Usage notes 
- Old Armenian did not have an IPA: [f] sound; in borrowed words it was replaced by փ (pʿ) (especially from Greek) and/or հ (h) (especially from Iranian); compare փիլիսոփայ, հրաման.
- Because this letter is a late addition, it has no numerical value.
- In Traditional Armenian orthography this is the 38th letter.
- Words with ֆ are either borrowings or are of onomatopoeic origin (though it is sometimes found in dialectal developments of some genuine Armenian words).
