Bengali letter Pha

In Avro Phonetic, type ph or f. Both spellings produce ফ. To keep two consonants separate, put Avro’s accent key between them; otherwise the input method may form a conjunct.

What sound does ফ make?

It is usually an aspirated p, with an inherent vowel in bare form. Aspiration means a small puff of air follows the p. A bare ফ carries Bangla’s default ô-like vowel; a vowel sign changes that vowel, while a virama removes it so the consonant can join another.

The letter’s shape developed over time with the Bengali script. That script descends from eastern Brahmi, attested in Bengal by the Mahasthan inscription, and passed through Kutila and Proto-Bengali stages. A palaeographic study traces Pha from the Kamauli grant through a cursive Torpondighi form; the angular Bengali form was fully developed in the 11th century. The script appears in inscriptions, copper-plate grants, literature, and religious manuscripts.

Why does ফ sometimes sound like f?

Pronunciation varies across Bengali speech. Some descriptions give an aspirated [pʰ] for western-central varieties and an f-like [ɸ] or [f] for eastern varieties. These are regional pronunciations of the same letter, not different spellings.

A nukta-marked form, ফ়, appears sporadically in spellings of Persian-Arabic loanwords to indicate an f-like sound. The 2020 ICANN Bangla-script proposal describes this practice as absent from ordinary printed Bangla. Plain ফ can already sound f-like in some varieties.
