Ethiopic syllable pu

It is the p-row’s u syllable.

Amharic learning charts place it where the p consonant row meets the u vowel column. Each sign joins a consonant and vowel. In Ge'ez and other languages written in Ethiopic script, read it within that language’s spelling; by itself, it supplies a syllable, not a complete message.

The script has a long history in Ethiopia and Eritrea. Some of the earliest writing evidence there is pseudo-Sabaean inscriptional writing from the 8th/7th centuries BCE. Ethiopic consonant writing for Ge'ez appears between the 1st and 3rd centuries CE. Vowel notation reshapes it into an abugida—a system where consonant signs change to show their vowels—in the 4th century CE. Amharic adopts the script in the 13th or 14th century. Most accounts connect Ethiopic writing to South Arabian consonant scripts, though the precise route remains debated.
