French verbal conjugation and morphophonology exhibit notable differences between spoken and written registers due to distinct oral and written morphosyntactic codes.
Paper [1] provides direct linguistic evidence regarding the unique verb morphology and inflectional system of spoken French, while Paper [2] investigates French corpora to distinguish between oral and written codes. None of the papers refute the claim, and papers [1] and [2] directly support the premise that French verb forms differ between spoken and written usage.
