Thai letter Fo Fa

Switch to Thai, then press / on Kedmanee. The standard Thai Kedmanee keyboard assigns ฝ to /; other Thai layouts may put it elsewhere. This is a text character, so its shape comes from your font.

What does ฝ mean?

It marks initial f; alone, it is a letter. Thai consonants are traditionally taught with identifying words: ฝ is paired with ฝา, “lid” or “cover.” The same consonant starts ฝน (“rain”), ฝัน (“dream”), and ฝรั่ง (“guava” or “Westerner”). Each meaning belongs to the full word.

Thai writing drew on Pallava, a South Indian script tradition, and developed through writing used for Mon and Old Khmer, an earlier form of Khmer. By around the 9th century, Sukhothai-era Thai brought these influences together. One scholarly account includes ฝ among ten consonants added because the earlier Thai letter set did not represent some sounds neatly.

The earliest date for Thai writing is disputed. The Ram Khamhaeng inscription, dated 1292, is often cited as the earliest Thai text, but its authenticity has been questioned; another proposal dates early Thai writing to 1219. Sukhothai letterforms continued changing after the 13th century.

Why is ฝ different from ฟ?

ฝ and ฟ both mark f, but have different tone classes. ฝ is high class; ฟ is low class. Thai tone depends on consonant class as well as vowel length, syllable type, and tone marks, so hearing the same initial sound does not tell you which spelling a word needs.

ผ is another lookalike, but marks an aspirated p: a p sound followed by a puff of air. As of 2026, fonts without initial loops can make notch height the clearest visible difference between ฝ and ฟ.
