In the first case, it is a vestige of the spelling in the word's original language (usually Latin or Greek) maintained in modern French, for example, the use of ⟨ ph ⟩ in words like téléphone, ⟨ th ⟩ in words like théorème, or ⟨ ch ⟩ in chaotique . In the second case, a digraph is due to an archaic pronunciation, such as ⟨ eu ⟩, ⟨ au ⟩, ⟨ oi ⟩, ⟨ ai ⟩, and ⟨ œu ⟩, or is merely a convenient way to expand the twenty - six - letter alphabet to cover all relevant phonemes, as in ⟨ ch ⟩, ⟨ on ⟩, ⟨ an ⟩, ⟨ ou ⟩, ⟨ un ⟩, and ⟨ in ⟩ . Some cases are a mixture of these or are used for purely pragmatic reasons, such as ⟨ ge ⟩ for / ʒ / in il mangeait (' he ate'), where the ⟨ e ⟩ serves to indicate a "soft" ⟨ g ⟩ inherent in the verb's root . </P> <Table> <Tr> <Td> </Td> <Td> This section possibly contains original research .
