=== Old Cornish orthography ===
Until around the middle of the 11th century, Old Cornish scribes used a traditional spelling system shared with Old Breton and Old Welsh, based on the pronunciation of [[British Latin]].{{sfn|Ball|Müller|2009|p=495}}{{sfn|Jackson|1953|p=67}} By the time of the {{lang|la|[[Vocabularium Cornicum]]}}, usually dated to around 1100, Old English spelling conventions, such as the use of [[Thorn (letter)|thorn]] (Þ, þ) and [[eth]] (Ð, ð) for [[dental fricative]]s, and [[wynn]] (Ƿ, ƿ) for /w/, had come into use, allowing documents written at this time to be distinguished from Old Welsh, which rarely uses these characters, and Old Breton, which does not use them at all.{{sfn|Jackson|1953|pp=67-68}} Old Cornish features include using initial ⟨ch⟩, ⟨c⟩, or ⟨k⟩ for /k/, and, in internal and final position, ⟨p⟩, ⟨t⟩, ⟨c⟩, ⟨b⟩, ⟨d⟩, and ⟨g⟩ are generally used for the phonemes /b/, /d/, /ɡ/, /β/, /ð/, and /ɣ/ respectively, meaning that the results of Brittonic [[lenition]] are not usually apparent from the orthography at this time.{{sfn|Jackson|1953|p=68}}{{sfn|Ball|Müller|2009|p=495}}
