tautogram
A tautogram is a text in which all words begin with the same letter. This linguistic constraint can be found in various forms of writing, from poetry and prose to tongue twisters and word games. The challenge of maintaining coherence and meaning while adhering to such a strict alliteration rule often leads to creative and sometimes humorous results.
The construction of a tautogram requires careful word selection. Authors must find synonyms or rephrase sentences
Examples of tautograms can be found throughout history, though they are not always explicitly labeled as such.
